"I can’t say enough good things about this place. I haven’t had a regular mechanic for oil changes, or repairs. I found this amazing shop, and came based on the reviews. I will absolutely return in the future, no doubt about it. They walked me through what needed future maintenance. Emailed me a full car care report, and made the process so easy. I definitely have already recommended them to someone I know. I will be back. Believe the reviews, they’re great."
"It is challenging finding an honest mechanic. This place has an honest owner with high integrity. The entire crew is very competent and hard-working. An absolute must go to for car repairs and/or maintenance done right. Love the explanations, follow ups and service tracking for your car(s). Highly recommend."
"This shop is conveniently located for me. Joe is really easy to communicate with and I love the software they use to show the problems with your car that include photos and videos. Pricing aligns with the quality of work. I definitely will continue to go back!"
"I went to fix my car at Doctor Auto and I am so impress for taking my car to their workshop . Joe and his guys are very patient and attentive to detail unlike some mechanics I have i had before. I was never disappointed taking my car there. I highly recommend Doctor Auto to everyone who wants to take care of their car health needs"
"If I could gives these guys 6 stars I would!They did an awsome job fixing my transfer case to my SUV they did it in a extremely timely manner. Explained everything that was going on in detail. They are one of the very few honest mechanics I have been to in a while. If your getting your car fixed hear you chose the right place I will exclusively use them from now on."
