New and used 2025 GMC Sierra 2500 trucks for sale near Mason, NH

We feel confident in the expertise at Swanson in terms of diagnostics and repairs. They have always been able to diagnose even complex issues with our Yukon Denali.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

High quality all around. Had a warranty issue they had me bring it right in. gave me a loaner vehicle and vehicle was completed before the end of the day.

My car buying experience with colonial Chevrolet was great. Charles Marks was very friendly and helpful along with the other staff involved as well. Love my new car and look forward to doing business with you. Once again, thanks Charles!!!

A lot of scheduled maintenance had to be done , and state inspection. It was done when promised and at a reasonable price .

Very good GMC LOWELL Made my experience very easy without making me feel like I was pressured to buy the SUV. They are all very professional!!

We purchased a Mazda CX-50 from Tulley Mazda in Nashua NH. We had a problem with the new vehicle and had to bring it to the dealer several times until the tech finally found the problem in a wire harness under the dashboard. We were given a loner each time we had to leave the car . Alex and their team are the best. They are professional in the way they do business. Have purchased cars from other dealers and never had such great service .

Everyone at Tulley was great! They even took my old car as a trade and gave me a great deal.

This is my first GMC purchase and I love my car. The staff at Tulley was wonderful. Thanks for making it painless and quick!

Fantastic Service and Sales department. My family and I jae purchased mulitple GM's and use Tulley Buick GMC's service department exclusively. Thank you Tulley.

Brought my 2011 GMC 1500 in for service for routine maintenance and the team did a great job as usual. I've been servicing my truck here since day 1. Thank you Dustin and team.
