I'm the owner of a 2008 Ford Shelby Mustang GT500. I was tired of unknowledgable service people at a particular Ford dealer, whose name I won't mention other than to say that it's located in Serramonte. I was in the market for some Recaro seats and went to Griffin Motorwerke where I talked to owner Terry Griffin. He was not only very knowledgeable about the product and about motorsports in general, he also hated Formula One Major Domo, Bernie Ecclestone, just like I did! What's not to like? I ordered the seats and when they came in, Griffin Motorwerke installed them flawlessly and at a VERY good price. I decided to give them a chance to do some installations of various new pieces on the Shelby. Terry ordered them and got me good prices on the pieces, and installed them to perfection. I did have one little problem, that being a rattle on the new left side muffler. I brought the car in on a Monday at 11:00 and waited while the rattle was investigated. Turns out that the Ford mount for the muffler was causing the muffler to rattle against the bodywork. The man who worked on my car actually fabricated a new mount and installed it for me in an hour. There was no charge, of course. Those recent modifications cost me just under $6000. I know for a fact that not only would they have cost me at least 25% more at any one of several garages I got quotes from, but when the work was done it was done perfectly, the above mentioned rattle being the fault of the Ford part and not of Griffin's installation. Griffin, as I said before, made it right immediately and at no charge. I'm a car guy. More accurately, a car NUT. I've been there, done that. I have never been so satisfied with the work, and so confident in the value I've received for work on my car than I have been with Griffin Motorwerke and its merry crew. It's worth a drive over the bridge from my home in San Francisco to have my car massaged at Griffin Motorwerke.
