Scott S.
Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

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.
