I created a Yelp account just to write a review of CS Motorwerks. I had a used BMW checked out by Chris. Not only did he inform me that if the fuel pump were to fail the repair might cost more than the car is worth after 150,000 mile SULEV warranty was up, he found an oil leak at the oil filter housing and told me that a gasket replacement likely won't stop the leak forever. I paid careful attention to how other customers were treated while I was there, and everyone seems really happy with the service. I know my way around a car and there's no doubt in my mind Chris is an extremely competent mechanic, and an honest guy. I may not wind up buying a BMW, but if I do I'll be happy to have an independent, expert mechanic I can trust in the area.
