Prompt, excellent service

by - Verified Customer January 31, 2014

I got to know some of the mechanics and it's pretty straight forward, no nonsense. They call and let you know what's going on. They keep you informed on what they are doing. Eddy the mechanic is an excellent mechanic.

We have been using them for years, they are great. Very clean and very accommodating. Their prices are very reasonable. Very professional, they always wash your car before you pick it up or bring it to you. They also offer a loaner car, which I used this last time.

by - Verified Customer January 28, 2014

After the job was done my daughter panicked, her cousin works there and he told her that she wouldn't be charged for the tow but when we got the receipt they charged us 600 dollars for the tow, and most other shops don't charge to tow.

They're just very honest and very reliable. Nice people, I love them. Every time I get an estimate it's lower then expected and when I take my car in for any service, it gets washed. Always has a loaner car for us, it's just a nice garage.

by - Verified Customer January 24, 2014

I think it was the owner, the guy at the front desk, was very helpful and gave me a loaner car. Just generally very helpful and honest.

Customer Testimonials

"I would like to thank Mike and Corey for their wonderful service. I called today for road service for a jump start and a problem with my hood opening. They were fantastic!!!! Will recommend Grand Prix to everyone!!!! THANKS AGAIN!!!!"
Carol W.

"I wanted to take the opportunity on behalf of my daughter and myself, to personally thank Joe P. for his wonderfully sunny disposition and his tremendous show of empathy and concern for my daughter’s situation with her Jeep this afternoon. When I arrived at the WCSU parking garage, he was not only, trying to get the Jeep started, but was also trying very hard to get Hannah to calm down, He kept a very positive attitude during the entire time…….."
Paula S.

"I have an 2013 Audi. Ran to the Danbury Mall late this afternoon for one present. Leaving in pouring rain, I hit an enormous pothole and blew 2 tires. I called Audi Roadside Assistance and they called Grand Prix to tow me. Greatest service in the area!"
