They are the best. They're the most professional and I always recommend them.

It's a great place to get your vehicles worked on.

Verified CustomerJuly 11, 2012

I don't have a lot of money, but I always go there because I know they are going to do a good job and if not, they'll take care of it until it is a good job.

Verified CustomerJuly 10, 2012

I think they have some of the most qualified technicians. Mason for one, also John P. And Greg's really good too. I've never had a problem as long as I've gone there.

Verified CustomerJuly 06, 2012

I've had very good experiences with them. They've done the work as promised, on time, and the price point has always come in exactly as I had been quoted. In one instance where they had missed something, they did the work and did not increase the price at all. I feel like they have been more than fair. I would go back to them anytime I need work on my car.

Verified CustomerJuly 03, 2012

Family atmosphere - the employees feel like they are part of the family there.

It was really good. Typically repair shops will under-promise and over-deliver.

June 25, 2012

They're not cheap, but they do good work and they stand behind it. You can count on them.

Verified CustomerJune 22, 2012

They did a great job. They were very friendly and there was no pressure. They know what they are talking about, very knowledgeable.

Verified CustomerJune 08, 2012

They're extremely fair and polite and respectful on the phone.

December 23, 2014

I really love these guys! And I don't use love lightly! I have a 2002 Hyundai Elantra GT, and I've had them service my AC, do a front end alignment, and just had my clutch replaced. I'm a 52 year old woman and I know a thing or two about cars and repair. I do most routine maintenance items myself and I don't trust most repair places. Usually they talk down to me and try to lie about what needs repair. But not these folks!! They are respectful, knowledgeable, and charge a fair price! This is the ONLY place I will take my car!

ADS found and fixed a vibration in my car that made it run as smoothly as the day I bought it. Great diagnostic abilities.
