New and used 2026 GMC Sierra 2500 Denali trucks for sale near Smith Mills, MA

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 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 bought a hard-to-find truck remotely. Joel Picchi made the sale easy, answering all my questions, and helping navigate the challenges of an out-of state purchase. It ended up being one of the smoothest purchases ever! Thanks to the team for getting this awesome vehicle delivered to my home in central Maine!

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...

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.

SALES REVIEW - HIGHLY RECOMMEND: After several failed calls with other dealerships in the area to find what we were looking for; we landed at GMC of Attleboro with Danny Jamgochian taking our call and answering all of our questions in a timely and professional manner. Danny was beyond helpful as we were purchasing two company vehicles that needed to be delivered to Nantucket. He always followed up with pertinent information [often on his 'day off'] with a zero-pressure attitude. Almost the entire transaction was handled over the phone which made our experience seamless being we were traveling over 2hrs away. Once we arrived at the dealership, Danny was focused on our needs and considerate of our time constraints. He also introduced us to General Manager, Gil Silva who helped facilitate us getting exactly what we needed/wanted with ease and with a family-oriented feel for our sales transaction. While we waited for the Business Manager, Dennis Yu to prepare all the financial paperwork - we were offered lunch which was a lovely touch. Before we knew it, our paperwork was ready to sign with the financing secured at the rate promised. While most clients dread going into the Finance office; Dennis was prepared and offered us the coverages that we needed without any pressure of selecting anything. We would highly recommend GMC of Attleboro to friends/family or anyone else reading this review! Everyone we came in contact with were friendly and made us feel like we were the only customers in the dealership. The facility was also very impressive, modern, clean/organized and offered many amenities throughout the Service Dept. [customer waiting lounge, snacks, TV, Wi-Fi] *Note: The second vehicle we were purchasing had not arrived at the dealership on the day we visited but that didn't stop Danny & the rest of the team at GMC of Attleboro from making the process of delivering it to us easy! The paperwork was sent ahead of time, the drivers delivered the vehicle in pristine condition, and they were both very polite and excited for us. Thank you to Danny, Gil and the entire team at GMC of Attleboro for making our dual vehicle purchase one we will never forget! It was truly a pleasure to do business with this group of talented individuals and we will certainly be loyal clients after our experience. Keep up the good work!

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.

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.

Everything was great. Sales man was clear and knowledgable. Manager was low key and gave a fair trade deal.

Justin was absolutely phenomenal to work with. At no point did I ever feel pressured, rushed, or on edge during the purchase of my vehicle. Justin was very friendly and fun to work with, he made the whole process immensely better. Even though I already knew what car I wanted going in, he took the time to explain all the extra features I didn't know about. Overall a very pleasant experience.

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.
