New and used 2025 GMC Sierra 1500 trucks for sale near Blue Hills, CT

I had an awesome experience with these folks. Friendly, informative, answered all of my questions. Jonathon was a joy to work with, as was Jeff. I have told all of my family what a great, stress free experience I had. If I ever have the need again it will be my go to place!

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

We were blown away at just how easy of a process it was to buy our car from this dealership. Everyone was absolutely fantastic. That includes Colleen, Matt, Kyle, Joe, Peter, and the rest. We would love to deal with them again. We are VERY pleased with the car, the service, and the general attitude of everyone there. I highly recommend them.

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

Thorough and courteous. Great customer service. Oil changed and issue checked out and repaired.

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.

Due to a national backorder of a part my truck took over 120 days to return. Gates GMC did inform me thru the process

Vinny at Sullivan's Northwest Hills was great to work with and to buy a car from. It was truly a good experience. He was very knowledgeable and let you lead the conversation. I will buy my next vehicle from Vinny the next time I need one.

My experience at Northwest Hills Chevrolet was exceptional. I was treated with the utmost kindness and respect, and accommodations for my special needs were made willingly, and in some cases, without my even needing to ask. My salesman, Phil Musmacker, made everything incredibly easy for me throughout the entire process (honorable mention goes to Brendan Elrick, who followed up on my initial request for info on the Equinox EV, and connected me with Phil). In addition, I never found any reason to question the pricing on the purchase order; everything was straightforward and exactly as I had been told, which is incredible considering my previous experiences with dealerships, where I had to fight to keep extras from being added to my order. Truly remarkable! I've already recommended Northwest Hills Chevy to a couple of friends! Thank you for a most wonderful experience (and I also really love my car)!

In maintaining our 2020 Buick Enclave, we have used Buick GMC Watertown Ct, since our purchase in September 2019 and have always received the best on time, reliable service and friendly customer service on our visits. The staff that reviews what service I am requesting will always review for possible upcoming recommendations of service as well. The cost and approximate time of completion has always been spot on.

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. 👌🏼

I dealt with Rich Noble and he was excellent. I am very satisfied with the purchase. I would recommend Rich or Blasius to anyone looking for a new car.
