Mufflers repair service near San Francisco, CA

Excellent quality of work and friendly staff. Tom Jameson

Came in for regular service. In and out the same day.

John is pleasant to deal with, asks pertinent questions, gives reasonable estimate as to time and cost. Delivers as promised.

The guys here are always straight forward. Good prices and I don't feel like I'm paying for services that I don't need. I've been taking my personal car here for awhile and the company I work for gets their services done here. John S. Antioch, CA

I love going to Clayton Valley Auto Service as Jeff and all those who work there are friendly, knowledgeable and do a very good job. When I had a check engine light Jeff's dad told me right off the top that it could be 4 or 5 different things and they would start out with the least expensive until they found out what the trouble was. I'm still driving that van around 5 years later. I really appreciate the great service they give. They are really great for routine maintenance, and wonderful when I have emergencies.

Brian very patiently and expertly diagnosed the reason for my engine suddenly shutting down for apparently no reason.

I have been taking my cars to Say Ray since 1969 - 43 years. When I was out of state for 7.5 of those years, I called them for help with my car and they were always responsive. I drive from Pacifica to take my car to their shop in Palo Alto. Would never take my car anywhere else! -Amy Vossbrinck
