Car looked better than new after repairs
An amazing experience with the service department and collision center at this dealership after my car was damaged by a fallen tree. The process right from the beginning was flawless. Getting the car to the dealership, getting the rental car, the time it took to get the parts and do the repairs was quicker than expected. The ease and efficiency of the repairs and the quality and timeliness makes Gates GMC. Jamie Laskow and his team get 4 stars from me! I will definitely recommend your dealership in the future.

Excellent buying experience!
My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼

It was a good experience.
It was a good experience. The lead sales man was a little on the rough side. But all was good.

Great service every time
I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.
