I was looking to do a track inspection, oil change, and cdv delete on my BMW. I found these guys through forums, and after reading the amazing reviews for their Dublin shop, I decided to give them a try since this newly opened Mountain View one was much closer. They're very involved with track days/autocross/time trials, which is a big plus as far as trust goes. The initial quote I got over the phone for the cdv delete was a bit high since they weren't sure if the exhausts needed to be removed, but the estimate was quickly lowered after they confirmed what needed to be done. During the service they found a few other things that needed work (they knew exactly what to look for as far as common problems on BMWs go), but they let you know and give you all the options before doing anything. You don't feel pressured, and they'll offer recommendations. If you've done the research on your car beforehand, everything they say makes sense. The overall feel of the shop is very clean and professional, and the people are friendly and passionate about cars. The prices are significantly cheaper than the dealer; while they're probably not the cheapest around town, for the quality you get it's a more than reasonable. I'm definitely taking my car here again.
