40 years of dealing with different people working on my cars and HG is in a class by themselves. Nobody better. Amazing experience every time.

Hands down best place to go for all your car needs!! Omar and his staff is professional, well knowledgeable and very trustworthy. Dont go anywhere else!

True car enthusiasts and professionals on every level. I will only take my cars to HG Performance. Whether the project is straightforward or custom fitment and performance, or racing applications, HG are true professionals. Not only technically proficient and exceeding expectations on delivering reliable problem resolution; but their communication skills are above and beyond other service centers (and Ive been to several others in San Diego and surrounding areas). If you take your car elsewhere, I wish you good luck in this climate of fewer and fewer true car people servicing and understanding the road going and track going cars of today.

We have had an E320 wagon since 2001. 242000 miles later and still going. It wouldn’t have made it this far without proper maintenance.HG will provide just what is needed, with superior efficiency at a more reasonable price.

Had my C8 Corvette lowered and had wheel spacers installed. This required a wheel alignment. Very happy with the process from start to finish. They are very professional and personable. Time was taken to understand exactly the result I was looking for and options were provided with pros and cons for each. The results speak for themselves. I can strongly recommend this shop.

I took my Jetta here for vehicle service, and I am so glad that I did. After days of problems and struggling with electrical issues, almost all my dashlights on (brake light, check engine light, abs light, epc light, steering light), and stuff not working (speedometer, odometer, and fuel gage) I decided to take it to this shop. I brought it in for an engine light diagnosis and electrical diagnosis, and within two hours my problems were not only diagnosed but fixed. Almost a week of struggling and being stumped, fixed just like that. I am so thankful!!The shop itself is easy to find, in a great location, and very nice. The staff were helpful, transparent, and professional. Highly recommend this place!!

All team members treated me with respect, made sure to treat my Lamborghini as if it was their own, and advised me with everything they were performing and bringing things to my attention (such as tire pressure) and asked if it was okay if they performed before assuming. I went in for an oil change, but was treated like I came in for a tailored Tom Ford suit. Already scheduled my next appointment for new tires!

Great service by Neema and Obi. Everyone is super friendly and knowledgable. Would recommend to anyone that I know.

Wanted to lower my Tesla a bit and purchased a set of coilovers. Didn’t know where to have the installation performed near my residence. Reached out to the company that produces the coilovers and asked them for referrals in my area. HG was highly recommended by them. Neema from HG was awesome and helped me feel comfortable with his shop doing the install. Top notch professionalism, and they really listen to their customers to make sure they get what they want done! Highly recommend this shop for all your car needs! Thank you HG for making my car look and perform like a Tesla should!Kenny Williams

What an absolute find! These gentlemen are as good as it gets. Arrived at spotless shop where owners of Mercedes, Aston Martin, Lamborghini and more had left their vehicles for work. A good sign! Ive owned multiple exotics and worked with countless high end shops and wish I would have discovered HG years ago. Top-notch work, good value, and down to earth management! Highly recommended.

I went back for final alignment after finishing the car build. I would not trust anyone else to put such skill and care into the alignment. Car drives amazing, handles so good. They are very knowledgeable and informative, you know you made the right decision after speaking with them.

Had HG Performance install a set of Mountain Pass Performance coil overs to my Tesla Model 3 Performance. I couldnt be happier with the results! Neema was extremely professional and knowledgable throughout the entire process. Work was completed on time with utmost attention to detail. Highly recommend HG to anyone needing aftermarket performance parts, repairs or anything else automotive related.

HG always does an incredible job. They have helped me with four different cars. From performance suspension, exhaust and tuning, to basic engine repair. It doesn’t get better.

Outstanding customer service. Neema and the team always go above and beyond to take care of their customers. I have been a loyal customer for 6 years and the level of professionalism has never wavered. They are always ready to answer any questions you may have and are dedicated to making sure you get the best price on repair parts. Don’t go anywhere else!

The team at HG Performance does a great job. Neema is a great service advisor and shop manager, the garage workspace is extremely well kept. Their mechanics do great work on some of the highest-end cars around, their workmanship is top notch. I have a newer Tesla that I wanted to add some performance parts on, and I was impressed by how quickly and cleanly they changed all 4 rotors, all brake pads and brake lines. They also replaced the tires, and there wasn’t a single scratch or blemishes; which is a testament to how they take pride in their work.The AG team is very experienced with high performance upgrades!

First rate experience all the way through. Finding a place to install performance parts on a Tesla is not easy. HG not only understood what I wanted done, they were able to provide guidance on how best to achieve my goals. Estimates were spot on and work was completed ahead of schedule.

Great experience. Easy to deal with and very straight forward with their process. Highly recommend

HG Performance is my new go to place for all my Tesla performance needs. The whole team there is passionate about getting the most out of vehicles whether youre taking it to the track or commuting. I cant recommend them enough.

I have been a customer for many years now, and I’ve always been incredibly happy with the service, quality, professionalism, and personalize attention that is provided. Not only have they done a perfect job with my sports car, but they’ve always given me advice that maximize my goals while minimizing my costs. During these pandemic times, they are doing a pick Up and drop off service that has been very convenient.

Highly professional and respectful. Would never take my vehicles to any other shop/dealership. Always meet and/or exceed expectations.

Our Boss 302 is serviced exclusively @ HG Performance since we regularly track the vehicle. These guys are race born/breed and know what they are talking about regardless of your type automobile. Most impressively, they are willing to thoroughly research before making upgrade recommendations. They are also willing to change their recommendations if they discover a better product. Finally, they keep a pristine shop and thoroughly clean your automobile of any maintenance related grime before releasing it back to the owner. See Neema & Andrew, you will not be disappointed as their name PERFORMANCE says it all!

These guys have always looked out for my best interest. No sales, they just really want to help you get what you need and want :) they love helping and passionate about it cars.I drive 45 min one way to bring all my cars to them and have for yrs. 💪🏼😎 thanks again guys !

My fiancé is very critical of where we take her Mercedes E350 and I heard nothing but great things about HG performance, and boy did they deliver!Omar assisted me through the entire process, got all of the services done at a MUCH more competitive price compared to other shops around town. Omar was very honest and transparent about what the car needed, and it is driving great! We thought about selling the car but after the all services HG performance did, we are keeping it for a few more years.Very grateful for the speedy and professional service from a grade A spot! we will definitely go back for my next service.

I had a very positive experience with Neema and the HG Performance team. Although I live in the South Bay it was well worth the trip. I appreciate the communication and the openness. I definitely plan to return for additional work on my vehicle.

These guys did a superb job on my 13 Mercedes ML 63 AMG. We did a Renntech R1 package, Renntech transmission tune, and an aftermarket heat exchanger. Were just waiting on my Capristo exhaust system and custom rims and tires. once they arrive my car will feel complete. I dont know how much HP Im putting out but I think its just under 700hp And 800 lbs of torque. My car is a beast and its totally street drivable. I will most definitely be brining all my cars here from now on. Neema and the guys did a great job. Very professional and high quality work. Thanks guys!

This shop is professional, does quality work and does so in a timely manner. Every interaction I’ve had with the shop has been truly exceptional, the sales manager is timely and efficient leading to a great experience. The work provided was solid, and done so without hassle on the day of my appointment. I’ll absolutely recommend this shop to those looking to improve their car.

These guys have their process dialed in! I have a 2017 subaru WRX and I had all maintenance done at the dealership for the first year and a half that I had the vehicle. I took my car to HG for the first time for simple body aesthetic mods (front lip, side skirts, rear spats). I was so impressed by Neema and the entire HG team that I decided to continue bringing in my vehicle for all basic oil changes and maintenance ever since.Since that time I have had their team complete all my additional upgrades including shifter upgrades (Boomba short shifter, boomba transmission plate, Perrin shifter bushing, Perrin shifter stop), had them complete my wheel, tire, suspension, alignment upgrades, as well as my intake, catback exhaust, accessport install, and custom etune for the car. They helped me navigate through all my options to select the proper setup for preference and cost. Every process has been straight forward, informative, and completed with perfection. Every time I have any questions Neema and his team are always helpful to provide insight, knowledge, and support for all the work they have done. Such a stellar team and will continue to have all my car maintenance and upgrades done with them!

HG Performance and the crew that work there are simply the best at what they do. The work they perform is second to none. I wouldn’t take my cars anywhere else.

Took my e92 m3 to them for some tuning work. Very knowledgeable about my car specifically due to its super charged. Will be using them again for sure. Shop was clean and organized. Good sign when you walk up. There were 2 gtrs getting work done as well as Mercedes and other BMWs. Looks like they work on anything. Thanks guys for getting my car back to running smooth.

Went to HG Performance looking for a shop to tune my 15 VW GTI, these guys were very knowledgeable, extremely responsive, answered several of my relentless questions about the parts, recommendations, CA restrictions on tuning, etc. Im sure Neema can attest to the long email chains, seriously thanks for everything, Neema!Even though there were supply and logistics issues on the manufacturers side of things, these guys got me setup for install when the parts came in, and I was in and out of the door in just a few hours. Very happy with the work they did, and the service they provided. These guys do some high quality work (I think there was a Lambo and a Viper in the shop the same day mine was in there). Will definitely go back when it comes time to have any more work done on my vehicle.

I had an amazing experience getting my brand new wheels and tires installed here. Neema the manager was a great guy to work with and his team did a great job on my car. I definitely recommend to others and plan on having my car worked on by these guys in the future.

Great service. True professionals. Highly recommend

I’ve been taking my ML 350 to this shop for years! They sure know their cars, especially Mercedes! Knowledgeable, reliable, reasonably priced and friendly. Super establishment!

Great job guys. Car was finished on time and with no issues. Also really easy to work with and knowledgeable about the products and services they offer. Thanks for taking care of me and my car!

Neema was incredible. My best auto shop experience. Super knowledgeable, fairly priced and phenomenal to work with. Couldnt provide them a higher recommendation.

These guys are amazing. Very knowledgeable and helpful for people who want to work on their own car. Took my EVO in for a more detailed inspection and they gave me a list of discrepancies and explained it very thoroughly and even showed me how and what to do. Never had an experience like that at any type of shop. Neema, your crew are great folks. Thanks guys. So happy I found a shop I can trust

Neema was great. Absolutely recommend HG to anyone who is looking to upgrade/customize their ride.

10/10 most recommended car performance/maintenance shop in San Diego!HG is one of the most professional and friendly car shops I’ve been to. I’ve had work done multiple times on my Evo X for performance and maintenance. Went from a stock Evo X to full bolt ons and never once had any issues. The car feels amazing after having them work on it. Definitely recommend to anyone who needs some work done!

Neema and his staff were very professional, kind, extremely knowledgeable and timely. After all was said and done; HG cut me a bill for much less than originally quoted. Neema said his technician was able to get a few things done quicker than projected, this spoke volumes to me about the integrity at this shop. I will most assuredly be bringing my car to HG for ALL future service and upgrades. This place is as honest a business can be.

Neema was super helpful, incredibly knowledgeable, and very professional. An added bonus: I was in and out faster than predicted! Thanks, guys!

Took my golf r for an APR tune. Staff were friendly and took the time to answer all my questions. Highly recommended!

Outstanding communication, professional, knowlegable. If you care about your ride I would not recommend taking it anywhere else.

First class company. They took amazing care of my car and evaluation and repair!!! I would highly recommend this company!!!!

HG provides terrific service. Extremely knowledgeable and professional staff. I only trust them to work on my cars.

Had the pleasure of working with Neema. Awesome, professional experience!

I found HG through a referral from one of my closest friends. I was close to losing all hope in building my 135i since I got ripped off multiple times by other shops. This was my first time building a BMW and I’ve learned a lot from some very expensive mistakes.What I had was a car that looked great on the outside ... but because of poor craftsmanship and straight lack of attention by previous techs, ran very poorly. There were parts I had paid to get installed or done that never materialized. So no one even knew what was and wasn’t in the car. It was a nightmare that lasted about 2 years.My experience with HG was quite the opposite. From the very beginning of our email interactions Neema was providing me with tons of much needed help and information about my car. I was pleased to get my invoice before I dropped off my car and even better they gave me an amazing quote!!As a former Marine I pay attention to every detail, and trust me their shop is beautiful!!! I didn’t even smell grease. Definitely one of the finest shops I’ve ever visited.And as icing on the cake these guys are true car lovers and super nice guys!I am so happy with the quality of their work I have decided that besides myself, no one else touches my car as long as I live in SoCal.If you love cars and really care about what you drive... this is your place.

Always great work... whee mounting is always without damage to wheels and alignments are spot on.

Omar and Neema are very knowledgeable, honest, their very flexible with their schedule, and friendly, very easy to talk too

I love coming to HG! The customer service is out of this world. I brought my car here to get an oil change and the technicians here were so accommodating. This is the first place I’ve taken my car where I haven’t had any issues getting an appointment in a timely manner. I definitely recommend HG to all of my friends!

Had a few services done on my vehicle at Heinz Gietz and they really took care of my car. Services included an oil change, oil pan reseal, 4 wheel alignment, AC service, wheel balance, and full vehicle inspection. Highly recommended. Good pricing & fast service! They specialize in Mercedes Benz, but you wont be disappointed no matter what car you have. Will come back in the future.

My17 GTR tire got slashed ... called them Tuesday, ordered the tires got em Thursday and installed friday..... no matter how small$$$ or big$$$ your projects or maintenance is they will always treat you special..... thank you HG for always coming in clutch!

The HG team is the best you can find. They are able to get stuff done. I was recommended to them and I was told Alain was the man in general and especially for mitsubishi evos. He literally knows every inch of evos and found so many major problems on a car i had recently purchased. They helped me get my evo ix that was in bad shape back to perfect so that i cam feel comfortable driving around with my kids in it. While i was there i saw supras, gtrs, stis, amgs, bmw m series, porsche 911 gt3 rs and turbos, and even a few ferrari 488s and a ford gt. People trust these guys with their cheaper cars like my evo and even$500k exotics. Will be bringing my evo back for power upgrades and maybe some of my other cars for upgrades as well.

Very helpful and professional.

Love these guys, just wish they were closer, lol

HG FTW. Passionate and knowledgeable people.

Went in for some aftermarket body work installations. Fast friendly service, high quality and very trustworthy.

Very simple, quick, and easy transaction. Thanks!

Brought in my high mileage w203 for a routine service to Omar after a friend recommended him to me. This place is not your average run of the mill service shop. Excellent customer service, very knowledgeable, and really chill people that works there. I usually feel intimidated in these kind of situations but here I felt like them. I also got a tour and saw the amazing exotics that they were working on too. Anyways, they helped me out a lot, and I mentioned that my gear slips a bit. Omar (Merc certified tech or something) in a heartbeat knew what was up and pulled the carpet from the passenger seat, did some uncorking, and saw a leak coming from transmission. Anybody else would’ve been like “ehhhhh - idk” but dude saved me money on the long-run by figuring the problem in a heart beat. Also, I think not only they service cars but they also supe them up and race them.

Always has had good service!

Great job! Thank you!

1st class establishment.

Awesome job!!

Amazing service

Great work
