Very good experience but there was still another problem after I had it fixed. I drove only one day then took it back to fix it which was some new problem which occurred before yesterday. I hope they can fix the problem.

Good work, ready on time and at a fair price.

by - Verified Customer December 20, 2016

One of the best places I have ever taken my car too. I drive a infiniti G37 coupe which I really take care of and these guys made sure that my car was up and running to its best with their suggestions and the work they did on my car. Definitely will remain my number 1 shop for maintenance and mechanical issues. However, I think the labor is a little overpriced for work that other mechanics can do for around 80 an hour.

by - Verified Customer December 20, 2016

Great service, great work, great people. We recommend this shop regularly and everyone loves them.

by - Verified Customer December 28, 2016

Very efficient and fair.

I have been taking my 2009 Mini to CC Auto since I got it. They are the only people who are allowed to work on this car. In my 43 years of driving they are the best repair facility I have ever dealt with. Keith, and Dan are the best and I highly recommend them to anyone with a car. I have never been happier with an auto shop.

I most recently went to Contra Costa Auto Service for a scheduled oil change and, as usual, the service was friendly, fast, professional, and first rate --all at a reasonable price. What more could a customer want?

by - Verified Customer December 20, 2016

Friendly service and helped diagnose the engine light and told me the reason and how I can fix it ..with no extra charge

All the guys at CCA are awesome

by - Verified Customer November 07, 2016

Work on my car was done in a timely manner. Loved the fact that I didn't have to make an appointment and they were able to work on my car with such a late notice. Great service.

by - Verified Customer November 02, 2016

Kevin and crew are excellent and know there way around vehicles. I have found them to be direct, honest, informative, efficient and reasonably priced.

by - Verified Customer November 22, 2016

Keith is a great manager, he is very explanatory, and very reliable. I will continue my fleet service of 18 vehicles, as long as he is there.

Clearly described requirements, pricing and delivered completed work on time-- great service!

by - Verified Customer November 10, 2016

The main mechanical problem was misdiagnosed, but ultimately cost less than quoted. There was no resolution to any of the electrical problems. The mechanic left oil/grease marks on the interior, broke a lens of an interior light, and did not tell me. When I asked about it (after the lens fell out on the way home), I was told the whole unit was one of the items which should be replaced anyway. Trouble is, the lens wasn't broken when I came in, now it looks terrible, and it still doesn't work. I would not recommend this shop to anyone.

by - Verified Customer April 23, 2014

They are great! Very knowledgable service at a reasonable price!!

by - Verified Customer April 17, 2014

The prices for the work are very reasonable compared to other garages I have used in the past and the guys are very personable.

by - Verified Customer April 16, 2014

Very honest assessment of what work was necessary to be done to the car now versus work that could be delayed into the future.

They diagnosed my truck accurately, and get it right the first time around. My truck is a 1999 with relatively low miles. Of course I can replace just about everything, but CCAS pinpoints the problem and fixes it the first time, and only as needed. I have not had that same experience with other mechanics.

by - Verified Customer February 28, 2014

The staff is very professional, they take the time to explain the work that will be done, and provide recommendations of work that may be needed in the future. Price for work is also fair.
