The second opinion that saves drivers thousands.
Our story
When your car is overheating, misfiring, or stranded on the highway, the last thing you need is a shop that talks around the problem. At Bob's Auto Service on Columbus Avenue, we start every job with a thorough diagnosis, walk you through exactly what we found, and show you the evidence, so you can make the right call for your car and your budget. Our customers come to us for second opinions and stay for the workmanship. Drivers have brought us dealer quotes in the thousands and left with the same repair done for a fraction of the cost, still running strong tens of thousands of miles later. When parts need ordering or budgets need flexibility, we work with you, not against you. We're open six days a week, and when it's urgent, we do everything we can to fit you in same-day.
What customers say
“I must say, my Toyota Corolla works just as I remember when we got it. I highly recommend Bob's Auto for their workmanship and communication.”
“A honest, reliable and trusted mechanic is hard to find these days, I was not upsold on anything. If my truck was stranded in San Francisco again, I am towing it to Bobs.”
“The Jeep dealer quoted me almost $8,000. They did a full service on the cylinder heads, resurfaced the heads and replaced the gaskets. All for a fraction of the cost. 20,000 miles later, vehicle still runs strong.”
