Brandon is excellent! I have an RV rental company directly across the street and he has helped me out so many times. I need someone with Mercedes expertise and he knows his stuff. Great customer service.Thanks always!

Excellent knowledge, expertise and integrity. Probably one of the best shops in the country for German cars. Were fortunate to have him here in Colorado Springs.

Although I didnt get any work done with Kleemann, Brandon took my call and gave me priceless advice about buying a used Sprinter van. I can tell he has a lot of experience and knows his stuff! His customer service (and just general kindness) is a breath of fresh air. I will definitely head his way - if I can just find the right van!

Very knowledgeable staff and fast service. Plus they have dogs, best shop ever.

Kleemann USA is the real deal! I took my Mercedes here for an ECU tune and to diagnose a minor oil leak. They gave me detailed and in depth information about the configuration of my engine/vehicle. The knowledge they have about European cars is evident. The ECU tuning produced noticeable performance gains; in addition they were able to diagnose and repair my oil leak at about 10%. Of what another local European shop quoted me. They addressed all of my many questions with patience and professionalism. I’m am only upset because I didn’t find this shop sooner.

This was a great experience. They were professional, knowledgeable and customer focused. I highly recommend.

Very knowledgeable about Mercedes Sprinter vans.

Awesome customer service and superb work!! Won’t trust anyone else with my car. Simply the best. And by the way, you won’t get this service with the price.

I have a 2017 Sprinter 144 high roof 4x4 and occasionally need things serviced. In the past I have driven to Littleton to get service at the MB dealer which is a bit of a hassle living in Colorado Springs.I found Brandon through a Sprinter group on FB and needless to say I am stoked that he is local which makes it easy for drop off and pick up (I was able to ride my bike to get it!)He knows a lot about my vehicle and helped educate me on what was wrong with it making sure only to do the necessary work required but leaving nothing missed.They have quite possibly the best customer service I’ve ever experienced. When I picked up my vehicle he even showed me the old part that was replaced. No one has ever showed me a replaced part they’ve just fixed it and hoped I believed them.They were so good about letting me know the status of my service. All of this really helped build trust and gain a customer and I’m here to spread the stoke about the work they do! Thanks guys!!!

Brandon and Lacie are both such kind and respectful people. Brandon diagnosed my Jetta and helped me find a GTI to replace it. Brandon is passionate about helping people learn about cars, as opposed to just telling them what do to. I will be taking my car to Kleemann for years to come!

These guys are Amazing. Very reasonable. Quick and Friendly. Will definitely recommend to friends.

My wife and I were recently on the hunt to purchase a vehicle and the assistance we received from Brandon and his crew at Kleemann USA was simply exceptional in every way! I would also like to publicly thank Brandon for all of his efforts in going above and beyond in ways that most other shops wouldn’t. The level of communication that Brandon provides on any project/job is on point! Brandon and his crew even helped us properly load an inoperable vehicle on a trailer for transport!! They have the knowledge to get things done and the shop is meticulously clean and organized to a level that is on par, or better than, any German dealerships work area that I’ve seen. Should you need anything as simple as a pre-purchase inspection to full rebuild I can not recommend Kleemann USA enough.

I would trust my Mercedes Benz only to this team. They showed the upmost honesty right away, my first ever concern was dealt with in a manner that anyone would only dream of. Thank you especially Cory Umemoto! He educated me rather then just selling me a product that i first came for asking. I will be looking forward to doing business with this company for many years to come.

Great service! Fair rates/prices! Fast turnaround! Quick to reply to messages and take calls. What else are you looking for? :-) I recommend and will be back!

Great guys over here. Came down to get my GLA45 tuned from Castle Rock. I was really happy with the results. Ive since traded that vehicle and will be having them tune my 2015 E63 in the next few months. Cant wait!

What a team they have at Kleemann USA. Brandon and Corys work is amazing, so much knowledge in those guys. Lacie the Office Manager is a sweetheart, they treat you with so much respect. I took my Mercedes SLK 320 with no start issues and in no time, they got it all figured it out. Ill visit them again in the future, for sure.

Fantastic place for ECM tuning! Great service and great stuff with a lot of knowledge. It was well worse the almost one hour drive from Denver. I could not be happier with the result on my 2014 E550. I will visit them again in the future!Highly recommended!!!!

They flashed my ecu and totally transformed my 55 swap for the better! I couldnt be happier with the support and service I received, especially from Cory. Shipped it out on Monday and it was back in the car Wednesday morning. Highly recommended!!

One of the most cleanest mechanic shops Ive seen in a long time management owner very nice people very intelligent treat you like family

Truly a valuable service, performed by professionals of the highest degree. Thank you!

The guys at the shop were very knowledgeable and helpful.I had the tune installed on my cl65 and am very very happy with the performance improvement.Lots of fun!!!!

They helped me multiple times by explaining stuff in detail to me and also looking over my whole car for me while they were installing stuff and found issues that I was able to get resolved promptly. Highly recommend for any Mercedes enthusiast, way better mechanics then the dealership and I have used both.

Kleeman!!! Brendan is the best!! He is very knowledgeable about what he does. As well he should be. I made the mistake of going somewhere else and he cleaned up the mess in a very timely manner. I will no longer take my car to anyone but this man!!! He is very fair priced and doesnt use cheap Oem aftermarket parts. He uses only the best parts for your car!! Thanks Brendan!!!

I highly recommend these folks for expert auto service and tuning of your German automobile.

Spent weeks researching an ECU tune for my 2015 SL550 with 7771 miles. After reading almost every thread on every tuning sub forum on all 3 major Mercedes-Benz forums, I decided to call a really good friend who lives in Esslingen Germany, outside Stuttgart. He owns 7 or 8 highly modified high performance Mercedes-Benz cars. He told me only to use either Kleemann or Brabus. After one phone call to Kleemann I knew who I was going to use. Cory was absolutely the most knowledgeable, polite and courteous person I spoke with on this quest. He answered all my questions, even the ones I had asked about 3 times before. The tune to the SL550 is noticeable in acceleration and throttle response.---BUT---the most amazing, extremely noticeable difference is in the smoothness and lack of running vibration from the engine. It used to be that you could tell when the car was running. Now, the engine is quieter, breathing easier from the Kleemann air filters and is much more refined. I cannot explain how awesome Cory and Kleemann were ! I never expected such a dramatic improvement in the overall engine dynamics of my car.

I have been bringing my cars to Kleeman for several years now. Brandon has always kept my Mercedes up to its TOP PERFORMANCE. I have never had a break down and the price has always been absolutely HONEST and REASONABLE . I get excited when friends ask me for a mechanic referral; I love sending them to the folks at Kleeman so they can experience the same EXCELLENT SERVICE and the COMFORT of knowing their car is well taken care of.Brandon even took the time to help me choose my next Mercedes wagon and check it over before I purchased it after my last was totalled in an accident. I couldnt be happier!

The folks at Kleemann USA are the best at what they do! We bought our son a used 2000 Audi TT for his first car. We live in a small town in Kansas, so if you dont drive a Ford, Chevy, or Dodge, getting your car worked on is no easy task. I know Brandon Grantham through a mutual acquaintance and decided to make the trip from Kansas to Colorado to have the car worked on. I have zero regrets about that decision. Brandon was honest about what needed to be done and, best of all, didnt treat me like I was an idiot. I know they have a lot of expertise in tuning high-end cars, but they did not balk one bit about the simple things that we needed to have fixed (coolant leaks, A/C compressor replacement, installing a new windshield washer fluid tank, etc.) He went above and beyond and even helped us source new rims for the car. We truly feel that our son has a safe car to drive now because of Brandon & Kleemann USA. If anything needs to be done to this car in the future, they will be the ones to work on it!

Expert knowledge and excellent customer service!

Sent them my ECU to do a flash and afterlagging 3 days on sending me the shipment box they told me their coder is out for another week. Not only that bud I ordered headers from them and a week later they are stilll not here.Very poor business ethics and very slow with everything. Wouldnt suggest to anybody unless you want to wait 1 month for your ECU flash.
