See What Our Customers Are Saying

"Had issues with my daughter's transmission. I was expecting a high bill to repair the problem that turned out to be coding errors. The result was a very small repair cost. Thank you for your honesty." - Bill Iannuzzelli

They treated me right! Not only was the bill less than what they estimated, they gave me a ride to where I had to meet some people while my transmission was being worked on. These are good people and were recommended by my go-to mechanic. - Daniel Roll

"Took my truck in for them to look at so I could get an estimate of how much it would cost. Took them a week to get to it because they were busy and it was a holiday weekend. Once they called me they told me what was the problem and gave me the estimate of $350, which honestly wasn't that bad. They fixed it and returned it to me the next day and was a bit cheaper than they expected. They are truly certified!!!!" - Joseph DeMoss

They found my problem instantly, a bit of a wait time to get in sometimes, but price is pretty fair, and they know what they're doing. - Andrew Temple
