2019 GMC Terrain Service
I delivered my Terrain to the service department and waited in the lounge. When the service was completed I paid with my GM credit card. The service department delivered my vehichle after it had been washed.

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.
