Great honest service ! A mechanic you can truly trust with your cars health.It can be really hard to find a mechanic you can trust that your not being ripped off, thats why Im so glad I found McGuinness Mechanics! I have nothing but positive things to say about their business.

I had a exhaust manifold leak caused from rusted and broken studs from the engine block. Seemed like a potentially unfixable situation as I took it to a few mechanics in the Marin area and they wouldn’t touch it and suggested I lift the engine to replace it. Took it to mcguinness mechanics and Joe helped me. He was able to fix it without lifting the engine and at a very reasonable price considering the situation. Joe is an actual mechanic and puts love, critical thinking, and expertise into your vehicle. Best shop that I’ve been to in Marin for my automative needs and recommend everyone to give them a try.

Needed brakework and immediately. He fixed a patch free of charge. Then, out of loyalty to him I paid for full brake job and fix of ac system. Once I started paying him, he started mistreating my vehicle, braking parts and refusing to fix issues that arose from his work. I went in twice a week for a month trying to get him to make the fix while he kept saying he needed more data, without driving the vehicle to even diagnose himself. Im almost certain he made me come to the shop over and over to do absolutely nothing with the vehicle. He held up my cross-country trip for a full month, laughing at me. He was happy to help me for free, but once I started paying him (about $1200) he had to kick me down over and over to continue to feel superior. It was a nightmare. I waited several months to cool off before writing this review and still cannot believe he did this. Hes too good to do an oil change, he told me. And if you want any insights to other issues, dont bother. In his words, he goes in with blinders on so he only sees the issue at hand. So if you are hoping for a helpful reminder to fill your fluids- it wont happen.

Very helpful and knowledgeable. Very reasonable

Always does a fair and reasonable job of fixing my 2005 Acura MDX. Nikki is great too!

Not sure why they wouldnt take the grumman but they were pleasant enough.

Exceptional service and incredibly high-quality work. Ive brought a variety of vehicles to them for the last twenty years: minivans, aging sedans, a truck, and a classic muscle car. In every instance the work was performed perfectly, and costing less than was originally quoted when they have discovered that I was mistaken about what needed to be done. Having just moved out of state I hope to find a new shop thats even remotely close to what Ive come to expect from the team at McGuinness.

Honest, skilled mechanics, been coming here for many years. Nice people!

Good prices (sure beats the dealerships) and very competent service. We have had them work on America, Japanese and European cars.

Super friendly staff, able to take my car in on short notice and fair pricing!

We love McGuinness Mechanics and highly recommend them to anyone looking for an experienced, friendly and reliable mechanic.

They do a great job machining flywheels
