Excellent Service ...Fairly priced ...Harry Jr and Sr both pr8vide excellent customer support and trouble shooters ...Highly recommend then for auto service needs

As a woman who doesn’t know a lot about cars, I’m always terrified I’m going to get taken advantage of at a mechanic. These guys have always treated me great and have been very open and transparent about the work they do and their prices. They do their best to explain the work they’ve done in a way I can understand. They live up to their name!

Harry provided excellent service! Picked up and dropped off my car. My car was serviced and I never had to leave work. That worked out great because of my busy schedule. I highly recommend this business.

Been going here for almost 15 years - In addition to our GMC Acadia, over the years Harry and his "Auto Master" mechanic Jimmy have worked on 3 different year Cadillac Eldorados, our 1989 Jaguar XJS V-12, and our 2011 Aston Martin DB9 Volante. I would send "Mom" here and not worry that she wouldn't get everything needing repairs done quickly, and at a reasonable price! Great place for new tires too!

Great place for auto repair

I got oil change for this place. It is very busy place and I made an appointment a week before. The service was fast and very nice. I recommen the place to everybody.
