After taking my BMW to the local shop in Pleasanton, and not being satisfied with the work they performed, I reached out to some friends who have BMW's and live here. They all said go to Ken at SAS, he the best. Well, they were right. This dude is as honest as they come and when you are looking at high cost repairs you want someone honest but also competent. Ken and his team at SAS are PRO's, Diamond certified. They are better than the mechanic's at the Dealership. I had SAS fix a botched Value/Timing cover job that the local BMW shop did twice (The BMW dealership did give me a refund so at least that was cool of them). Since the repair at SAS I haven't had any leak and the other work I've had done, has been top-notch. Hands down if you have a BMW or another German made car, go to these guys......... you won't go anywhere else again.
