"Have had several of my cars serviced here over the years - they are always straight up: The work is done as required, they do take a look to see if there are other things to address and if so, they actually SHOW you what is up, not come up with a crazy long list and unleash a sales guy to scare you into more repairs. Fair price points as well - highly recommend!"

"I requested an estimate and included what I thought was wrong with my car. They did a thorough job and were extremely honest! They could of easily taken advantage and over charged for work I didn’t need right away, and they didn’t! I will definitely return for any repairs my car needs!"
"I had been with these guys (Pete and Joe) to take care of my various cars since 1997. You won't find more honest mechanics anywhere and both are fully knowledgeable, fully capable and the pricing is good. Sometimes I bring my car in with 3-4 things to do...and they will call back and tell me "One of those items don't really need to be done" I can't rate these guys high enough! Six stars would do!!"
"I had a few electrical issues they fixed then something else happened electrically again called Joe he said drop it off again and I didn’t have a ride home so they arranged for a worker to bring me back home in my car then I got my car back the next day with the issues that I explained that needed to be fixed all working and got my inspection sticker done as well I know certain things are still iffy but at least it’s up and running until we’re able to get a new car after the winter I explained that it was just a local car for work and I just wanted to say these guys go above and beyond to help their customers happy I’ve always trusted them with my cars and now they just proved themselves once again thank you so much for everything you did to get my car fixed"
"I've been going to Doctor Auto since I got my first car. Joe, as well as all of his employees, do a good job with the work they do, as well as giving good explanation with what they do or plan on doing to your car. They take the time to really know their clients and remember their vehicles. I always recommend my friends and family to get their cars taken care of here."
"The service here was very good. I had to have a replacement tire ordered and it arrived in a short amount of time.I recently had another major repair done on my car-the mechanics are knowledgeable and explained everything to me.Competitive prices,too."
