Professional, honest, fairly priced, knowledgeable, competent mechanics who perform service in a timely fashion, keep you updated, and have a sense of humor. I have a 2000 VW GTI GLX that I have taken there two or three times since I moved to SF, and I have been well-treated every time. They were recommended by a friend who has a 2001 Jetta; both of us have had experiences where we called in the morning with a problem, were told to come in that day, and weren't charged for a very quick fix or tweak. I particularly appreciate the lack of upsell and the amount of information they give me about the problems they're working on.They have a shuttle for mornings, but iirc you have to find your own way back. The T-Third swings right by there, so it's easy to get to via MUNI. For one major series of repairs, they had to schedule me a few weeks out, but as mentioned above, they seem happy to take a quick look at your car the day you call them with an issue if they think it is a no-brainer to fix.
