New and used 2026 GMC Sierra 2500 trucks for sale near North Westport, 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.

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!

Overall I had a good experience. A salesperson explained things to me without being overly pushy. No complaints. I think I was treated very fairly. I did end up purchasing a vehicle from them and in my opinion got a very good deal.

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.

Courteous & Professional throughout my purchase. Looking to purchase, ask for Sayed, you won’t go wrong!

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!

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!

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!

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

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.
