You took my car to get its smog check after my oil change. And my car was sparkly clean inside & out!

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.

My rear bearing was completely screwed and they fixed it in a short amount of time but what was even better was the price and most importantly the customer service. They were extremely nice and made sure I understood the problem. They fixed my car in no time. I will definitely come back to them! Although hopefully I don't have to!
