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

by - Verified Customer July 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.

by - Verified Customer July 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.

by - Verified Customer July 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.

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

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

by - Verified Customer June 25, 2012

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

by - Verified Customer June 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.

by - Verified Customer June 08, 2012

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