Amazing serviceMost courteous and honest staffThey do not do any unnecessary work that is required

Had air suspension issues. They took care of the problem and we’re extremely helpful. Definitely the only mechanics I trust.

I have been using PerformanceWerks for many years for all my vehicles and have always been pleased with the work and friendly service. Ive never had a complaint about work done. There new location is great and Im glad they are nearby in Naperville. Certainly easier than taking my Porsche to a dealer and less money plus you actually can talk to the person that works on the cars. I would recommend them to any person who needs work performed on their cars.

Made it easy to set up an appointment and have my bimmers brake fluid changed - at a reasonable price

The team at Performance Werks has been professional, helpful, and their work is excellent.

Love this place! I will not take my Range Rover anywhere else. They always take care of me here and I highly recommend them. 🤩

Mike, Justin and the entire team at PerformanceWerks are truly top notch. Not to overstate it but I trust them unflinchingly. I find it somewhat rare these days where critical service providers are not only exceptionally talented doing quality work, but these guys truly make you feel like they have your best interests at heart. Only the facts...no pressure, fair pricing, and always accommodating. And Mike the owner...what can you say. He runs a fantastic operation and to date each visit has exceeded my ever increasing expectationsThanks Mike and the whole team. I truly admire what you do and know that you have a customer for life.

I trust them with my car for years now. Mike and his team are the best. Great service and very professional.

Mike and Justin run an incredible business. I would highly recommend PerformanceWerks to anyone looking for great customer service and impeccable work.

Performance Werks is a professional operation. Mike and his staff are knowledgeable and reasonable in their pricing. I have brought my Mercedes there for years and always have been extremely satisfied with their work and pricing. Have sent several friends there and they all have pleased with their service and pricing. I will never need to bring my car to a dealer again.

Performance Werks did a great job as usual they analyzed the problem got back to me promptly about the issue and then corrected it. Their prices are also extremely competitive especially when compared to the Mercedes dealership. Great job Mike and Justin! Thanks

Honest and personal service. Big dollar cars in the lot and still take care of the older high-mileage imports too. Although I dont want to go back (really, who WANTS to get their car repaired?), they have a repeat customer for sure.

I bought my dream car a few years ago and had no idea where to take a German top dollar piece of equipment. After searching long and hard surfing through hundreds of reviews, I found Performance Werks to be the one that had the most positive accounts of satisfied cust. I am so glad I had tried them first. Not only are they more than qualified to take care of high dollar cars, their is no one that can beat their prices. I found them to be incredibly professional and a genuine pleasure to do business with. Beyond taking care of my car, they are willing to do general maint. on my brand new truck. Justin is always helpful in getting my vehicles in asap, and Mike seems to take the time to have a friendly conversation with his customers. I would never take my car to anyone else for general maint. or service of any type. Hope you guys are around for decades to come.

I have always taken my BMW to PerformanceWerks and they are hands down the best! Customer service is top notch! The crew is extremely friendly and helpful. Most importantly, they are honest. They even try to save you money but cutting back unnecessary fixes and prices are very reasonable. I want to appreciate everyone at Performance Werks for taking good care of me as a customer and my car.

Always friendly and professional. Owner, Mike always goes above and beyond to make sure your car is fixed properly and they offer courtesy cars.. big plus. Justin/ Service Manager does a great job at accessing issues-repairs needed and communicating. We will be back.

I wish I would have seen the previous reviews on the BMW long story short STAY AWAY IF YOU HAVE A BMW .....this company got me out of over 4 Grand in suppose to be repairs and my car is still not drivable with an oil leak

I have a BMW X5. Since it was out of the the BMW included service option, I am taking it to PerformanceWerks for all services including Oil Changes. Break Services. I also changes Alternator once. The charges are very competitive compared to BMW dealer service centers and I am very happy with Quality of service provided.

I take my Mercedes to these guys, and they have been really great. Their price might not be the cheapest among all independent shops, but if you want peace of mind, go to them. Their work is perfect.

They are always so helpful, and they always give you the best prices you can ask for. Whether it’s a new BMW 7 series, an older Lexus, or a top of the line Bentley they can do it all. Mike has saved me a fortune throughout the wars compared to what the dealers charge. And, I trust his work more. There’s no reason to even look at anyone else in the area.

Performance Werks has the most experience technicians I have ever met. Their customer service is impeccable, they took great care of my car by noting down anything that needed to be fixed. Overall great experience and i recommend this shop to anyone who has a European or exotic vehicle.

These guys are great..friendly, professional and a lot better value than the dealers..

Great service & very reasonable cost. Ive been using these guys for several years for my past BMW and most recently Audi car.

I have my Porsche Cayenne serviced in Performance Werks three times. They are wonderful. The Porsche dealer wanted to charge me $3800 for the rear break service. It cost $2600 in PW. The Porsche dealer asked $1200 to replace rear door hinges. PW fixed it for $480. Also I wanted to install my own mud guards. They did not charge for the labor! They are very friendly people and the office is like a yoga place, clean and neat......... I strongly recommend them.

Have been using them since they opened and have always been more than satisfied. Much more reasonable than going to the Porsche dealer. Really appreciated the loner this time!

Ive been a loyal customer since I bought my first BMW in 2012. Work is top notch, very reasonable cost, great knowledge of cars but especially European vehicles. They are my exclusive mechanics for my latest BMW now. I wont go anywhere else and I trust them completely.

I have been a customer of PerformanceWerks since shortly after I purchased my Mercedes SLK 280. I would not think of taking the car anywhere else! The work is thorough, done right the first time, and very reasonably priced. You cannot not go wrong trusting your car to PerformanceWerks.

The shop was very communicative on the status of my car. They did a once over to identify any other potential issues, and told me what needed to be replaced now, and what could wait. Highly recommend.

I find Mike and Justin to be excellent and very fair. I travel out of my way to go here. I have for many years now. I highly recommend PerformanceWerks.

Wonderful! I have had my BMW worked on here and was so impressed by the level of service and value I have received. Justin and Vic are amazing and so easy to work with. They communicate really well and I know they are taking the time to do the best quality work for the best price. I wouldnt take my cars anywhere else!

PW has been maintaining my cars (08 Porsche, 11 BMW, 10 MB) for over 5 years now. I am very satisfied with their service and recommend them to others, without reservation.

Ive been here for my wifes Porsche Cayenne Turbo S and these guys are great... They generally go out of their way to help fix any issues with the car even if its not being fixed in their shop. Vic called NTB, negotiated the price for all 4 tires for me... Highly recommend them for all your auto repairs need. Thanks guys!

Amazing service. Amazing price. Gets the job done Right first time! Kudos!

Loved these guys. Very hands on approach with the customer. Vic treats people like family and makes sure everyone is happy and coming back again. Our car was fixed at a decent price and we even got tips on how to do some of the things ourselves.

I had my 2011 Audi Q7 worked on and Justin from performance works was awesome...he worked with me regarding payment and changed my wiper blades without charge. He also quoted me a price which was way lower than the Audi dealership with my repair.I highly recommend this place.

Very professional and clean shop. They deliver the highest quality of goods and services at a fair price. Its the place to go for European cars.

Performance Werks provides the best honest vehicle work on your car, that will give you peace of mind.No haggling, no trying to sell you something your auto doesnt need, just highly trained auto mechanics providing the performance your vehicle deserves, give them a try.

Excellent service with obvious concern for customer COVID 19 safety.

If you’re looking to have your vehicle serviced or repaired, look no further. The Staff at PerformanceWerkz are friendly and very attentive to your vehicles need. I trust them to perform scheduled maintenance on my Mercedes Benz Metris.

Amazing work on my BMW and for a great price! Medinah made me feel at home when waiting for my car! Highly recommend!

Great

This shop is the best independent shop in the area. You get expert repair work at a fraction of the cost. Blake and Mike are both highly trained and experienced technicians. They will actually show you what is happening with your car so that you have a better understanding of the repair. I always feel as though I am being treated honestly and fairly, and have full confidence in their ability to repair my BMW. I highly recommend their work to anyone looking for professional, quality service - needless to say, I wont be taking my car any place else for repair.

These guys are excellent! As a woman, its tough to find a mechanic who wont take you to the cleaners or talk to you like you wouldnt understand. They have always taken the time to explain whats going on have always been fair in pricing.I will never take my cars any place else.Its really refreshing to find an honest mechanic!Thanks!

Really good work & personal attention. I wouldnt take my 2001 bmer anywhere else.

The staff here is always nice & very professional, one time. Give them a try!

These guys do a great job. Not only is their work top notch, but their customer service is excellent. I wont use anyone else to work on my car. I recommend using these guys for any of your vehicle repairs.

Mike and his team are the absolute best. I drive over 30 minutes each way to Aurora to have my BMW serviced there.

Vic treats everyone who comes in like family. He really values his customers and does great work. If youre looking for reasonable prices, quality work, and awesome employees, look no further than PerformanceWerks!

Great customer care been going to the Mercedes Benz dealership but this guys at performance werks are really good and fast. specially Vic his one of the owners here he will do everything he can to help out.great customer care highly recommended

Called in on Monday with a wiring issue for my 03 911. the car has been to 3 other shops and 2 of them were Porsche dealers. Mike gave me a call and even a day later with whats going on. I picked up my yesterday night and its running great! I highly recommend this shop.

Very helpful and knowledgeable. Provided quick service for a major and complicated repair. Highly recommended.

Met Blake at the shop and got the brake fluid changed on my 06 BMW 325xi. He charges a fraction of the price compared to that of BMW! Real honest guy and I had nice chat with him about cars in general. This IS the shop Im going to in the future!

My 528 was towed here after a sudden engine power loss on free way. these guys fix it with very reasonable price. Thank you!

We have taken our Land Rover and Volvo to Mike for a few years now. Mike is VERY knowledgeable and professional. These guys are HONEST and provide QUALITY WORK. I highly recommend Performance Werks.

I absolutely love love love Performance Werks! Mike, Vic and Justin are the most trustworthy and friendly team. I wouldnt trust my high end vehicle with anyone else.

Very nice people, but not competent with BMW autos. I have invoices for 5 months of their effort with the same issue. They spent quite a bit of time chasing a fundamental engine issue. I spent over $2000 for them to guess at solutions. I guess thats the guarantee, you spend more and well keep working on it. I was realizing they were over their head and asked about their diagnostic tools and learned they were knock-offs!I had more experienced mechanic evaluate the car issue and he immediately identified the problem.Nice guys, but they rely too much on meters and diagnostic tools. They are probably OK for simple straight forward issues, but if you need a serious mechanic you may want to push your car to next mechanic.It sounds like others have had the same experience. Incompetence is not selective.I rated them a 1 star - I spent lots of money and got lots of new parts which didnt resolve the problem.

I ALWAYS feel very safe after these guys work on my car. They have the best ‘refreshment’ section and their prices are much, much better compared to others.

Blake recently serviced my Porsche 911 and I think he runs a great shop. He was ready for me when I arrived for my scheduled appointment and promptly completed the service I requested. PW offers a comfortable waiting area, great prices, and they have very good knowledge of imports. Hey, if I can take my baby to these guys, you can too. TRY THIS SHOP!

Best service for high-end vehicles uses OEM parts for repairs and is a certified Bentley repair shop. Have only been getting my 2010 BMW 535xi repairs done here since my first visit. And from what I can tell they have no problems dealing with repairs that involving dropping down BMWs complex xDrive. Prices at times have been 50% of what a dealer would charge. And I can personally say they show their appreciation of customer loyalty. Everyone who works there is extremely knowledgeable of all of the cars they service. Ive always been able to get my car setup within an appointment within a day or two and they always have finished my repairs in an exceptional amount of time. I normally have only worked with Mike and Justin and they are phenomenal. My most recent visit I worked with Vic for the first time and hes is just as every good as everyone I have worked with here!

Ive been taking my Audi A8L to Performance Werks for over a year now, and it has been nothing short of exceptional. Let me explain.Certainly you need to have a competent mechanic working on your car, but what sets these guys apart are their HONESTY and PROFESSIONALISM. I brought my car in recently for an oil leak, but the extent of the issue was a bit more than what met the eye. After providing a quote and timeline, Mike offered me a loaner car for no extra charge and let me hold onto it for the entire duration of the repairs.While repairing the oil leak, a secondary issue of engine misfire was identified. Instead of gouging me with extra parts and labor costs, Mike worked with me to find a fair approach to managing the secondary issue.In the end, he took care of spark plugs some ignition coils all while waiving a ton of additional labor. This was an unnecessary gesture but speaks to the value Performance Werks places on their customers and relationships.No, fixing euro cars isnt cheap. But in past experience, Ive paid equal or more at amateur shops for less competent work. This place is the real deal and I couldnt be happier to find a shop that I trust and can rely on.

One of the best experiences Ive had at an auto shop and thought everyone else should know! Quick and efficient diagnosis of the problem and they fixed it in no time. The price was right, (way less expensive than the estimate of where I usually go), and the attitude of the mechanics was AWESOME! These guys will take care of you.

So glad to find PerformanceWerks for repairs on my BMW. By far the best prices and fantastic service!

Great place for service. The staff is courteous and very knowledgeable. All repairs completed timely and correctly. Would highly recommend!

We have taken our Lexus to Performance Werks Aurora/Naperville for a few years now. Viq & Mike is VERY knowledgeable and professional. Lexus of told on my RX350 there is steering fluid leak when I have 50K miles on it, but when I took it to Performance Werks, they said I do not need any repair. I have 110K miles and I have not done any repair for the steering fluid leak. not only that I dont even any oil leak in my garage. I highly recommend Performance Werks.

I trust these guys for necessary repairs and maintenance to my 2006 BMW. They are all around good people with great prices - these guys are legit!!

I was looking for a good shop to work on my BMW, other than the dealer. Read the reviews and decided to give them a try. My X5 has a high pitch noise when driving in gear, was concerned it was transmission. They looked at it told me the belts need to be changed, I thought great better than a transmission. When picking up car noticed high pitch still there. They looked at it again and said water pump, I had them change it. Took car home and the high pitch noise got worse as I drove back home. Called them, I was told they stand behind their work. They looked at it again told me power steering pump needed to be replaced. Before I let them do anything, I took it to the dealer, turns out it is the transmission. Spent over $1,000 with performance works that I didnt need to.

Took my car here about 1 year and half ago..My 07 BMW X3 would not start. Saw excellent reviews on this place and decided to have the car towed here. Spoke with Blake and his diagnosis was engine is bad and needs to be replaced. Went ahead with his recommendations and had the engine replaced.Update. 1 year and half later and forking over $6500 to this shop. Car now has oil leak. Took it to local shop in Texas (we moved) and diagnosed oil leak due to valve cover gasket and oil filter housing ~ est. repair cost $1600. Mind you this should have been replaced along with all other gaskets when performing engine replacement. Should valve cover gasket and oil filter housing LAST more that a year and half?BEWARE! Always check their work! Unfortunately, I did not as we were busy with moving to Texas.

Very friendly, prompt services, and reasonable prices! Will definitely use them from now on!

I have a 2013 MB GL 450 and after my dealership quoted my car needing new brakes and some other work, I called Performance Werks. I spoke with Vic, whom was very knowledgeable and accommodating. After they looked over my car for the repairs the dealership said it needed, Vic called me and told me I did not need new brakes and told me why. They had the other repairs done that day for about half the cost the dealership quoted me. They have gained my business for life! I appreciate the honesty and integrity from this company and Vic provided the best customer service experience for me.

I am so glad for all the people who wrote positive reviews for this shop. They were right on the money. If you need honest work, fast service at a good price, you should definitely check out this spot.

The staff and service are great! The prices are reasonable too!

Great customer service, Justin and Mike know just about everything when it comes to these cars. Saved mine from becoming scrap. Thanks guys!!

This is absolutely the best place to get your car repaired, they are very knowledgeable, and they will go the extra mile for you. No matter where I live I will always come here for service, I have been coming here for the last 8 years. When you visit ask for Mike or Justin they will take care of you needs.

Justin was great and very knowledgable about M3s. I am not local and needed a PPI on a car so I called up Justin and he was able to look at it within a day and give me great advice. If I was local to Chicago I know id be a regular.

I bought a 2012 Audi Q5 late July and brought it into PW for the 85k service, and to have an engine light issue checked out (As I pulled away from the dealer after purchasing, the engine light flicked on and they advised me to take it to a shop. Not what youd expect after purchasing a new car but, hoped it would be a minor fix)PW diagnosed the problem an emissions issue, stating it needed a new air pump-$1000 fix. Not the news I wanted to hear b/c in a few days I would be moving permanently to CALIFORNIA, and obviously driving the car. We told PW (Justin) to do a VERY thorough check on the car and iron out issues with the air pump b/c I would be making a 3000 mile trip in a few days. They assured me it would be checked out. When I went to pick my car up the next day, everything seemed to be fine, no engine light.2 days later, I start my trip to CA, engine light turns on again. I call PW and tell them I have no choice but to bring the car in again because I NEED to leave town. They agreed and said it was probably just a connection issue - it was not. The workers had installed a FAULTY pump (how this happens, I have no idea. I would hope any new parts they put in a car would initially be tested BEFORE installing). The problem now - they claimed b/c it was a Sunday and no shops in the area were open, they wouldnt be able to find a new part before Tues. As my car is filled with everything I own & sitting in their shop, Im rethinking my moving plans. Luckily, they were able to find an Audi dealer that was open and had a part available. They told me it would take a few hours to install it. Of course Im not happy about this b/c Im meant to be on the road at this point, but I would rather have the problem completely fixed before I start driving. Few hours later, everything looks great and Im happy to say goodbye to PW...but the issues dont stop here.Now Im on the way to CA, and stop in Albuquerque for the night. The next morning Im about to leave, engine light turns on AGAIN. At this point I know its the same issue. I take it to an AutoZone where they scan the code for free and quickly. Once again, the same issue with the air pump pops up. I call PW to tell them the news AGAIN. Justin says he doesnt know what the issue is, but hell connect me with a shop in CA for when I arrive, and theyll help me with the cost of repair if its an issue with their scope of work (should have gotten this in writing). Nice of him to do, but the shop he connects me with is at least an hour away from where I told him I was living. Annoying, but nbd.Once arriving in CA safely, I take my car to the new shop right away. They diagnose the problem as clogged valves the air pump connects to-ANOTHER $1,000 FIX. Of course I expect PW to pay for this since it is related to what they were quoted to fix, and Justin had SAID they would cover. Its something they should have picked up the first 2 TIMES I took my car to them anyway. However, Justin says they wont help pay for any part of this b/c it wasnt a direct issue with the air pump itself..? Seems ridiculous they could install a part without ensuring the full system is clear and functional. (*Ill also add Justin had said if you were still in IL, we would do anything to help you, but thats not the case WHAT? You OFFER to spend your time and money to get the issue fixed if I were in town, but as soon as I leave, you dont front me the cost for it, and suddenly its not your problem anymore? Doesnt make sense*) After many phone calls, explaining my frustration, PW agreed to refund me the labor cost for their job - $250.Now that I have saved enough funds to have the real issue resolved with this new CA repair shop, Ive just received a call that the clogged valves have damaged the pump PW installed. Unsure at this time if a new pump will need to be installed, but PW has caused me at LEAST $1000 worth of ADDITIONAL issues.I would never recommend PW to anyone. Ive been dealing with this problem for 3 months and still am extremely upset with how PW handled (or didnt handle) the situation.

A+ shop. They service premium imports without charging premium rates. Theres an impressive number of certifications on the walls for Bentley, BMW, and more. Its nice to see that ambition and desire to do things the right way.I typically work on my BMWs myself, but always bring them to Mike and Blake when its a tough task...they always come through for me.

Best prices, great service!! Very honest and caring! Thank you Vic!

Great service and fair prices. I highly recommend this business.

If I could give Mike 10 Stars I would definitely do so as he had just replaced my alternator in my Lexus yesterday (without even having an appointment) for a much fair and reasonable price than the Lexus Dealership would have...Mike came across honest and reliable; he even installed the 100% Denso alternator part that normally comes in all Lexus vehicles...also, the Towing Company recommended PerformanceWerks and I am 100% glad they did...I would too! BTW, the bonus going with PerformanceWerks was when Mike heard I was going to wait 5-6 hours in his shop because he had to order the part, he gave me a free loaner vehicle that was brand new to use during the repair time...Wow, what an awesome individual with great customer service! Thanks so much for your help and generosity Mike!!! I found my trustworthy shop in Napervile!

It’s the biggest scam ive ever encountered, charged me thousands of dollars for work and parts i did not need and probably tampered with the electronics to run codes. If you know anything about cars stay as far as you can away from this place!

Honest people. Marcos a great personThank you for fixing my bmw x6 with less.

Performancewerks does great work and at a fraction of the price of others they have great customer service as well Justin is always on top of things and makes sure stuff gets done and is very professional

Michael and Justin are the most professional bunch of guys that I know anytime that I have a BMW need I come to performance works first thanks so much for taking care of my cars 🚗 These guys are certified BMW Mercedes and Bentley mechanics

I have to say the best experience I ever had. Mike and Blake are upfront and were very professional. I was reffered by another client of theres and I drive 20 miles just to get my Audi A8 serviced. They saved my almost 50% from what the dealer was charging me,using only Audi parts. AMAZING! There follow up with me was second to none. I have recommended them to many of my friends and family.

These guys came highly recommended by my friend at the BMW dealership. I drove 30 minutes away from my place thankfully to find a very accommodating and professional performance shop. I have taken my M3 to Performance Werks twice now and I am very impressed with the quality service, attention to detail, and follow up. Unlike my last shop, these guys don’t treat me like a stupid girl with a fast car and they do not try to sell me performance parts I don’t need. They don’t just run a quick diagnostic, they go the extra mile to figure out what is really wrong. It’s a small shop that schedules up quickly, but they have managed to accommodate my crazy schedule and make me feel like a valued customer. I also appreciate the fact that I am not given a vague guess as to when I will be getting my car back. I recommend these boys and I won’t be returning to my old shop, Performance Werks has my business.

My father drove here to get an oil change from Rockford, IL and he was blown away; by far the best service experience he has ever encountered and these guys know what theyre doing and charge a fair rate. All in all, if my old man thinks it great then it has to be true...see ya later Mercedes service of Hoffman Estates.

Performance Werks have done an outstanding jobs on my 2 BMW cars. Superb service and very cost effective. Both Mike and Blake have an awesome knowledge of imported cars and dedicated service management. Much better than BMW dealer services. I will hight recommend them to anyone.

Great place to get your BMW repaired. They did the brakes on my 335i BMW at about 2/3 the cost that BMW was going to charge me. Also pointed out some things that BMW wanted to do, but they told me were not needed and saved me a lot of money. Very honest...not something you find these days in Naperville or Illinois. Will continue to take my BMW there and the wifes mercedes.

I needed pads and rotors and a few other small things for my s5 stumbled across this place on Google gave em a call. Told Mike what I needed he said hows Wensday which didnt work for me so he said drop it off tomorrow put your keys in the lock box which I wasnt to happy about but luckily when I got there another guy was there locking up the place and was able to put my keys inside. Picked my car up the next day alls well saved me over $1,000 bucks from the dealership great service, no hassle, good work!

I have been taking my cars (BMW, Audi, Merc) here for the last 6 years. as soon as the prepaid dealer maintenance period is over. Performance werks has provided great quality service at a fair/reasonable price on a consistent basis. They are very knowledgeable and highly experienced when it comes to Luxury european cars. I have recommended them to 2 of my colleagues, who now use performance werks on a regular basis.As an example, the dealer told my wife that we need to spend $1800 on recommended transmission service because it had 35000 miles on it. When i asked Vic about that, his reply was to print out the official service recommendations sheet, walked me through it and showed me that the recommendation was to do that service at 60000 miles. And if he were to do it, it would have been around $1000.Knowledge, quality and integrity at a fair price.

Trustworthy, friendly and they do a fantastic job maintaining my BMW. Much more reasonable prices than the dealership.

Mike & the whole crew are always professional and knowledgeable.Work is done ✅ right & on time.Thanks, Ken

Had my differential and coolant changed here. They did an excellent job, very friendly, great to work with all around. I would highly recommend them to anyone.

Mike and Blake are 2 of the best Mechanics I know. I own a Merc S600 and they have provided care to my car with pricing that cant be beat by anyone. Highly recommeded!

This shop is AWESOME! I bought a private party 328xi and was trying to address a slight shimmy. Had a horrible experience with a local tire shop breaking both hubs when over tightening the lugbolts with an impact wrench. The shop corrected that, but the shimmy was still there.Took it to PerformanceWerks and Blake took his time and thoroughly addressed the situation..did some research and got the correct adapters for my wheels which were missing. Aftermarket wheels so it was difficult to determine the right adapter size and he spent a lot of time making sure the measurement was right for a $5 part...and he did not charge me for that addl. time.He also allowed me to use his own extra set of wheels and tires to test drive my car to rule out my wheels and tires. He has a very intelligent and methodical troubleshooting approach.The addl work I needed (shocks, rear diff leak etc) was VERY reasonable as well. Not only does this shop have cheaper labor rates than a dealer, but they prove over and over that they are honest and truly care. He also takes his time and explains things and saves you money wherever possible. Definitely NOT shop that milks you for everything they can get. Im sure thats why they have so many positive reviews and repeat happy customers. Definitely found the import shop we were looking for.

Best service in town they fixed the problem from the first time.Thank you PerfomaceWerks team.

Vic is great, but he is no longer at performance Werks. They did a repair that was unnecessary and the car doesnt run, dont bother taking your car here, nightmare situation.

Great customer service and flexible billing. I took my BMW X5, 4 or 5 times and had good experience

I brought my mercedes ml350 in because of check engine light and transmission limp mode they were able to diagnose and fix the problem very easily and affordable !!! This is for anyone who owns foreign vehicles its very hard to find an honest shop that does quality work without the headaches these guys are by far the best shop ive ever been too!!! 10 stars good job guys !!!!thanks for your hardwork

This place has its pros and cons. Customer service needs work, and better flexibility for weekend repairs for customers who cant be car-less during the week since they have no shuttle or rental service.

Originally took my 328 to BMW (Naperville) and they provided a repair quote that was more than double of Performance Werks....the BMW dealership does provide snacks though. However, if youre interested in quality work and great prices, do yourself a favor and call Performance Werks.
