There’s a reason why I drive through Boston traffic to work with the team here! The service department is fantastic and always returns my car looking much better than I left it, and my sales person is a pleasure. I’ll be getting my third vehicle from Colonial in within a year! See More

Does your GM Bill McConnell threaten all the customers? That is not a good way to sell cars I had the craziest ordeal with him tonight. I simply wanted to buy a car and he called me all kinds of name...s and was very upset that i took three hours to have the car checked out by my mechanic and told me off. then later called said he was sorry only to go crazy again before we could close the sale....

I will never use this dealer. After 3 days of trying to reach them, being hung up on and without any response via e-mail, they do not have their stuff together. Go to someone else.

Only have been in twice for maintenance on my 2014 sierra and both times have been great. Short wait times and polite staff.

I would encourage anyone in the market for a new GMC to visit Colonial GMC and ask for Brian Mahan. Straightforward, personable and respectful. A true pleasure to do business with.
