New and used 2026 GMC Sierra 2500 trucks for sale near Hanson, MA

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.

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

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

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

I had a great experience working with Nate Resendes. He was incredibly attentive and knowledgeable, taking the time to answer all my questions without ever making me feel pressured to buy. I appreciated how understanding he was about my situation — I’m not quite ready to make a purchase yet, but wanted to get a clear idea of what to expect. He gave me helpful, honest information and made the whole experience comfortable and informative. When I am ready to buy, I’ll definitely be coming back to work with him specifically. Highly recommend!

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.

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

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

Great customer service - easy to schedule appointment and even provides me with a ride back to my office!!

I had a fabulous experience purchasing my Sierra. There is NO pressure which is a breath of fresh air. They are extremely knowledgeable, kind, trustworthy, and you will feel very confident in buying from them. I go there for service too and everyone remembers who you are and they come up to you to say hello. If I could give them more stars I would. This dealer is exquisite.

Incredible customer focus. Had an issue with my 2020 Silverado. Had to drive from Wareham to Marlborough so I pulled in to Robertson GMC, never once believing that I would be able to continue. Within an hour they had it diagnosed and the part shipped for next day delivery. I was thrilled but was totally surprised when they offered me a rental to continue with my trip. They called the next morning and the truck was repaired by 10:00. I returned to pick it up and they had even washed and vacuumed it. Incredible customer support, especially the Service Advisor, Jim Morrill. What a pleasure it was dealing with Robertson GMC!

Courteous service and a capable repair staff. Even an around town vehicle if you are waiting.

Alex was great very nice easy to work with dealership was easy truck was detailed and fulll tank ready to go

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

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!

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.
