Diesel engine repair service near Fremont, CA

Absolutely the best Mechanics & Customer Service in the business.

I had a great experience with William Michael Automotive. I brought my car in with a weird noise and they were able to quickly diagnose the problem and propose a solution. I was blown away by the emails I received from them with photos of my actual problem along with diagrams of how it should look and function. They really go out of their way to make the customer feel comfortable that they are getting great service. I really appreciate the level a detail they took in their work and would highly recommend them to anyone I know looking for a mechanic they can trust!

I had problem with the engine with my Mercedes and was cautioned about visiting a dealership. A friend recommended this shop and I drove there .Although it was far from San Jose I am glad I did that . They did a good job and fast and were very courteous... I am very happy with their workmanship and reasonable prices. I just wanted to share my good experience with everyone. Two thumbs up! Azar S.

I took my car to Alex about a week ago. One of the best mechanics I've ever been to. He took the time to check what's wrong with my car and got back to me with a fair estimate and price for labor. I recommend California Auto works to anyone looking for a FAIR price and a good family business. Anyone telling you otherwise is just looking for a cheap deal versus good honest work.

Howard and Chad always take care of me. They are totally dependable, honest, and capable. No baloney. They are not the cheapest place in town, but you get what you pay for, and they always stand behind their work.

Jorge of Baja's auto tech has done several jobs for me over the last year. He has been honest with me and given me a good price every time. He has not tried to convince me to do something that doesn't really need to be done. He trouble shoots problems like a master mechanic should and only does what makes sense to do. I'm happy that I can trust him and that he gets my job done quickly. I highly reccomend him!

When I first came to California a year ago, my clutch ground completely away from my 1999 VW Jetta and I needed a repair. I was expecting to pay $800, but was billed only $630! Al was terrific and my car drives great now. Al and Jeff at expert mobile have a combined 60 years of experience (I asked) and have incredible service. Since then I go to Al for everything, knowing I will walk away with great service, at a low price, and that he got the job done quickly. I recommend Al to anyone in need of a trustworthy mechanic. (He even helped explain to me that I didn t need some repairs that would have cost me a lot!)

We needed our neglected vehicle all better. Steve and his team looked things over and did everything we needed to get back on the road safe. Thanks, guys!

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.
