Catalytic converter repair service near San Francisco, CA

Family owned business, caring, knowledgeble. Very friendly staff. I had a tricky issue and they fixed it in a timely manner.

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

I have used A+ for my cars for a number of years now. The work is always done correctly, on time and I am treated politely. They explain things to me in terms I understand. A huge plus is the ride TO and FROM work so that I am not bothering colleagues to get a ride. I recently had to use the dealership and it reminded me why I go to A+ instead, polite, on time and professional.

I brought my BMW into Holland to assess an issue that I was having with my transmission. After the assessment, Holland said that I needed a new transmission, which would cost approximately $8,000.00. I got a 2nd opinion from another repair shop and they said that Holland was grossly incorrect and that my problem was only a minor computer issue. It was an easy fix, my car runs fine now, and the cost was a hundred bucks. I am terribly upset that Holland presumed that I should replace my entire transmission and spend $8000 when it was only a small issue with my car computer that should have been diagnosed correctly in the first place. I trusted Holland and I was misled.

The BEST tire place! The atmosphere of the business is very relaxed and friendly, and they make sure that if you decide to wait there, you're totally comfortable doing so. But more importantly, they're fast and efficient, polite and courteous, and have good pricing with no tricksy upselling. I've bought tires here and had them checked just for tire pressure; nobody made me feel dumb for requesting that simple service. The wonderful person who helped me today was Kurt, and if you ever get to deal with him, he's an angel. He was super kind, knowledgeable, and respectful. He's a huge part of why Redwood General Tire will continue to get my business for years to come.

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.

Excellent quality of work and friendly staff. Tom Jameson

I've been going to Autowise for years. The people who work there are friendly and professional. Right now my family owns and maintains 5 cars. Autowise services all of them, and I have never been stuck by the side of the road in any of them because they do such good work. That is very important to me, especially when my children are behind the wheel. As far as price goes...cars are not cheap to maintain! I would recommend that you shop around. You might find a better price, but remember the old saying...You get what you pay for!

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.
