New and used 2026 GMC Sierra 1500 trucks for sale near Sterling, MA

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 .

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

If I could give more stars I would I have never been comfortable dealing with dealerships and car salespeople in general . I did a lot of searching at different places for my new vehicle .I found what I was looking for at McGovern Westborough .Here I met Ben Fasano . I was pleasantly surprised .He was extremely helpful in not only finding what I wanted with absolutely no pressure. But Even after I purchased the vehicle he has been helpful with the registration and all that goes with putting it on the road. Not only Ben but all the people at this dealership made me comfortable with purchasing a vehicle here even though it’s 30 miles from home. So far so good !!

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

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.

Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.

I had an excellent experience at McGovern GMC Westborough. Ben, my salesman, was fantastic—he was helpful, never pushy, and kept great communication throughout the process. He really listened to what I wanted, respected my budget, and even took the time to get to know me while sharing a bit about himself, which made the experience feel personal and comfortable. Omar in finance was just as great—super friendly, honest, and transparent about everything. The dealership itself was clean, well-maintained, and in a very convenient location. Overall, the entire process was stress-free and enjoyable. I’d highly recommend them!
