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

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.

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

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

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!

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.

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.

Great service. Pleasant greetings. Timely Call backs when messages left. Accommodating, efficient and fair price for oil change and tire rotation. Travel the distance for good service.

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

Every department at Robertsons has knowledgeable employees that are extremely friendly and helpful. I have purchased multiple cars there and the process has been all around easy because of the employees. And the service department always gives updates if needed and has your vehicle done at the promised times

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.
