I always receive excellent service from Colonial.
I always receive excellent service from Colonial. Last time they stressed how important fuel injector cleaner is for my vehicle, however this time they didn't mention the cleaner and when I brought it up they said they would take care of that next time. How important is it really? Just left me wondering and thought I would mention it.

My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.

Our 2013 Terrain was purchased from Colonial back in
Our 2013 Terrain was purchased from Colonial back in 2016. It has almost 222,000 miles on it. Still performing well. We always get great service at Colonial. Kimberly is our service representative. She does a great job. This time was a fluky thing. The only key we had was lost and we had to get a new set of keys. A frustrating situation was made easier with help from Colonial and Kimberly.
