We have taken two cars to Rennwerks, starting in October 2010. The first is a Porsche 911 C4S. Every time we were greeted quickly and Mike, the owner, seemed very knowledgeable. They replaced a water pumped and valve cover gaskets. Each time they communicated with us frequently about the car and kept us up to date. The second car is my son's M3. It had been losing power and driving rough. Mike and his colleague solved the issue quickly and showed us the problems on the car and explained the reasons why the issue occurred. Great Service!

Take your car somewhere else. I took my car to this shop between June and November 2010, 7 times, for initially one issue, and some maintenance. They were not able to figure out the initiall issue, and they have introduced more issues in the process, due to air leaks etc. Everytime I paid at least 1.5 hours labor, a total of more than $6,000, half of this money went to the problem they couldn't fix it. The rest was maintenance, i.e. brakes, but even still the brakes are making noises. Most importantly, they told me my all 4 oxygen sensors were dead, and they replaced it all, still same error. Anybody with a little bit experience can know the probability of 4 oxygen sensors failing is nearly zero! In addition they have crashed my car, their insurance paid for it, but still the car is not same. I am even thinking about sueing them for fradualent repairs, and crashing my car. Take your car somewhere else. They may be nice people, but certtainly something wrong in this shop
