Tune up service near Danville, CA

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.

General auto repair shop that also specializes in performance tuning. Whether it's a simple oil change, a diagnostic or a full on engine swap we take pride and care in all of the work we do. Our mechanics are ASE certified and have many.

Great shop and crew! Very honest. Best auto shop that care about your needs and concerns. My Honda runs great!

This place is GREAT!!! Bo and Todd are so nice and helpful. They did not try to overcharge me like some places and I really appreciate that. I'm so glad I've found a good mechanic and I will be sure to recommend my friends.

This is the place I will return again and again! I am very impressed on how they handle the entire process of my car trouble. I was changing out my drive belt and ac belt, not only their price was more than reasonable but their work was spot on! I was able to get in and out fast. Also ask for an oil change while I’m there and it was not a long wait at all! They were upfront about the cost and give me a detailed break down. They also warned me about taxes and fees that may apply later at check out. No hidden cost that will surprise you later. Overall, I am very pleased with my service and I will return with both my cars for any service needs. Thank you RC auto for taking care of my car! Ben Chang
