I had a great experience with Wayne over the holiday weekend. During my drive up to Santa Rosa from San Francisco, my AC stopped working and the temperature gauge shot up to H. We made it up to Santa Rosa without overheating, but I did not want to risk driving down without getting my car looked at.  (Especially because I was driving very precious cargo - my friend and her 5-year-old daughter!) Long story short -- I found Wayne through Yelp.  He was open on the Saturday after the 4th (of July) and said he'd be able to check out my car within the hour.  He was friendly and funny, and I immediately trusted him. He was able to diagnose the problem, had the part that needed replacing, and fixed it for me by the end of the day, just in time for the drive home.  His prices seemed very reasonable (my friend commented that the diagnostic cost $50 less than her's cost at an SF shop). If you're looking for a shop in Santa Rosa, give them a try! - Sandy S.
