New and used 2026 GMC Sierra 1500 trucks for sale near Sagamore, MA

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

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.

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!

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.

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.

My family had a great experience working with Battles Buick GMC. The staff were all very helpful and professional. They made the car purchasing process smooth and pleasant. Would definitely recommend to family or friends.

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.

We Couldn't ask for better employees or service at a great dealership offering professional confidence and target for customer service and satisfaction. I've purchased numerous GMC/Buick products from them and couldn't be more satisfied.

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.

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

Both Mark & DJ made the car buying process easy. They were both professional and a pleasure to deal with. This is the fourth vehicle we?ve bought from them and will not consider buying from any other GMC dealer.

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.
