New and used 2026 GMC Sierra 2500 Denali trucks for sale near Bliss Corner, MA

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.

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.

Best car buying experience I’ve had so far! Derek was awesome!!! I would definitely buy from Mastria again!

Go see Mike at MARTYS best place on the south shore to buy a truck...

Had an amazing experience with Nate! He was kind, knowledgeable and was able to assist us from start to finish!

Excellent as always; second vehicle acquired from Marty's GMC

Can't get better than Marty's! We purchased a new 2021 Acadia through Marty's this go-around and had the pleasure of doing business with Paul. Great sense of humor, but even better businessman. We showed him a great offer from a competing dealership up in NH, that every other local dealership around here told us was impossible to make. Paul disappeared for a few minutes came back and said I can match that! So happy with the car, and happy we got to continue our relationship with Martys.

Michael Gentilucci was very kind, courteous, and professional. I inquired about remote start on my 2019 GMC Canyon and he was very knowledgeable on the process of installing it on my truck. He ordered the part and I can't wait to have it installed. I originally just went there for an oil change, but service was so great I decided to let them install the remote start as well, rather than my local GMC dealership. The kind and courteous service is worth the extra few miles to drive.

I had an awesome experience getting my new car at Battles. Janet Green the GM and Jeff Battles were amazing to work with. Will definitely buy my next vehicle from there as well as my husbands. Excellent facilities, snacks and drinks, charging station for my cell phone while I waited. Service was also friendly. Overall A experience.

as usual the service is amazing. I have used the same dealership for years

I?ve always had a good experience at Marty?s GMC. The Sales Consultant, Corey Amara was professional, knowledgeable, and very helpful in my new vehicle purchase.

Everyone was very friendly, not pushy did have to negotiate a bit but that the nature of buying a car. Dennis the Salesman, very responsive and reliable. Did not take long, wasn?t there all day which I was impressed. Overall great experience and would definitely buy from them again.
