Verified CustomerNovember 23, 2012

Those guys are like the best. I've been going to a lot of different shops and I've been going to those guys for the last six years and they are the best. They're honest. They're not that expensive and just do good work.

Verified CustomerNovember 23, 2012

They were fair and they explained the problems to me and they took care of it.

Verified CustomerNovember 21, 2012

I thought they were very knowledgeable working on my Mercedes and they found what was wrong with it. I took it to the dealer and they couldn't find what was wrong.

Verified CustomerNovember 19, 2012

They did a good job, and had it done when promised.

Verified CustomerNovember 17, 2012

What I would say is the owner or the person that manages it, I don't know her name but she's very friendly and very fair. Very flexible. Very accommodating. She makes sure that you're satisfied with the work done and she's very upfront.

It's highly personalized service. They offer a lot of options at varying prices. Depending on repairs that need to be done, you can have them done immediately or down the road.

They quoted to me how much it would be to repair my sun roof. It was almost 2000 dollars. They looked online and found a sun roof at a much lower cost. They really work with you. Very nice customer service. As a female I have felt ripped off before at repair shops. I didn't feel that way at all at this shop.

Verified CustomerOctober 15, 2012

I've been going there for 3 years now and have referred many people there. They are extremely trustworthy.

I took my 2001 Jeep Cherokee Limited to them for the first time by recommendation of RepairPal.com and though they stayed within the guaranteed price by repairpal, even the low end of the estimate, I was disappointed with the service.

They replaced the heater core, which requires removing the entire dash and when I received the car back my check engine light went on within 10 minutes of driving the car home and it was not on prior to bringing it there. Also the on/off knobs for the heater blower did not work so I had to turn around and bring it back.

When I asked them what happened during the work, could they have possibley loosen vacuum lines while working so closely to them, causing the code and check engine light and they denied that they could have done anything to have caused the problem.

I find that very hard to believe and the lady that ran the desk, the son and mother are the owners, and she even became rude to me that I even was inquiring if they could have done anything to the emissions/vacuum lines. It is entirely possible and highly likely. She handled the problem very unprofessionally and even very rudely.

She refused to investigate further and now I have a CEL on with a vacuum leak somewhere immediately after the work they did on my car. Be careful with what work you get done there and if you suspect they did not do a good job, do not go back!!! I will never return and they put a scratch/dent in the front passenger door, which I did not even bother to mention. Don't bring your car there!!

Great People! Great Service! I was having a rough time with the tow company (should've used them). The angel at the front desk talked me off the ledge and made me feel secure about leaving my car there. They did great work, explained everything, and we're fair all the way.

Excellent customer service!!! These guys do outstanding work, and only $65 bucks an hour!!!! They went above and beyond for me and I couldn't have asked for a better experience. Thanks guys!
