New and used 2026 GMC Sierra 2500 trucks for sale near Danielson, CT

I had routine maintenance done on my Encore. The service as usual was excellent. Very friendly and professional service staff. They are a pleasure to work with.

I had a problem with the radio settings (would not stay at my settings) and groaning rear brake noise on my new 2021 GMC Sierra. I took it back to the dealer where I bought the truck and they did nothing and basically told me to "live with it". Wendell Jordan (service advisor ) for this dealership solved the problem with the rear brakes (had rust in them) and replaced the radio module which so far has kept the volume and sound settings. I would highly recommend Chevrolet Buick GMC of Attleboro for their service because they care, especially Wendell Jordan!

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.

I got an unsuspected flat tire on a Monday morning on my way to work-Dominic, the service advisor got me in and out of the dealership within 90 minutes 🥲 thank you so much for helping me

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

A quality dealership in all respects. Knowledgable personel in sales, finance, parts and service. We?ve been dealing with this dealership for nearly a decade since moving to RI. We have either purchased or traded in several vehicles with the promised hassle free process. Our vehicles are always serviced/repaired right the first time at a reasonable cost.

I appreciate the prompt and excellent service that was provided at Paul Masse Buick GMC South. Special thanks to Peter from the service department who worked hard to assure that all of the issues with my wife's pickup truck were resolved. Thanks to Paul and the great team he has assembled.

Two and a half years later our salesman, tom frat, is still going above and beyond for us!! He arranged a service for my truck, got me an appointment and the truck fixed in no time. This man is a true people person and knows customer service like the back of his hand. Tom needs to be recognized for his ability to ALWAYS TAKE OF THE CUSTOMER FIRST!

Service tech was very helpful in ensuring the service due was completed and provided, based on the mileage, recommendations for my next appointment. Overall a great experience.

An amazing experience with the service department and collision center at this dealership after my car was damaged by a fallen tree. The process right from the beginning was flawless. Getting the car to the dealership, getting the rental car, the time it took to get the parts and do the repairs was quicker than expected. The ease and efficiency of the repairs and the quality and timeliness makes Gates GMC. Jamie Laskow and his team get 4 stars from me! I will definitely recommend your dealership in the future.

I recently had an outstanding experience purchasing my 2024 GMC Sierra AT4 at Gates GMC in Windham, CT. From start to finish, the team at Gates exhibited clear communication and professionalism, making the process seamless and stress-free. What stood out the most was the transparency and honesty in every interaction, with no hidden agendas or surprises. I felt valued and understood, and they made sure all my questions were answered. I highly recommend Gates GMC for anyone looking for a reliable and customer-focused dealership. Thank you for an exceptional experience!
