Read Our Auto Repair Customer Reviews

Once again, great service. Had my truck towed to their shop with a leaky clutch. It was ready in about 2 hours with two fresh master/slave cylinders. I called another shop before calling On-Site, and they couldn’t get me in for 2 weeks. From now on On-Site will be my first call, always. Fast work and fair pricing.

Steve R. / Santa Rosa, CA

Great experience! I needed a battery for my SUV, and this site totally came through for me. Very quick response time, they had the part I needed in stock and I was in and out, battery installed, within a half hour. I will definitely be back!

Carla N. / Santa Rosa, CA

Definitely found my new auto place! Will only bring my car here from now on, they know what they are doing and are top notch customer service. Honest and dependable!

Tiffany K. / Santa Rosa, CA

I’ve been taking our cars here for a few years and have recommended countless people. These guys are honest and reliable. I feel like a have a friend who is a mechanic. I trust them completely.

Angel W. / San Francisco, CA

Brought my Honda 2002 CRV in to get a diagnostic and Chris and Cory were fabulous. So honest and explained my car problems in layman’s terms which was so easy for me to understand. Definitely my new go to place.

Jennifer M. / Yelp

Super nice guys. Got a quote through Yelp which beat the others I received. Was able to get me in quickly and service took the time expected. Gave a suggestion to another vendor for a service that they couldn’t perform. I definitely will be back!

Stephen R. / Santa Rosa, CA

My dad, brother and I have been getting all 4 of our cars serviced at On Site since moving here in 2013. In those 5 years, they’ve always gone above and beyond what you’d expect from most mechanics. Cory is professional and honest with you, from communication to pricing. Chris is one of the most talented mechanics in Sonoma County.

Josh D. / Santa Rosa, CA

Second time I’ve used them for the routine work. Last was  year ago during a previous visit to Santa Rosa. No change in thoroughness of their quality work and their patience with their customers. Oh…I didn’t mention their rates. Totally competitive! So, we have great people, top quality work, and great rates. Regardless of the complexity of the auto work you you need, this is your first stop…period.

John L. / Glen Ellen, CA

Thank goodness for these guys, seriously. My fiancée and I just moved to the area and so happy we came across their Yelp page. The reviews are true!! They were able to get my Prius from the tow yard and to their shop within literally an hour after contacting them and kept us updated all along about the repair. They were extremely helpful with providing us support regarding our insurance questions.
