New and used 2026 GMC Sierra 1500 trucks for sale near Whitman, 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.

Fantastic job by Neil and the team at Central. Easy process and overall great experience.

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!

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

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!

Jake was a wonderful and knowledgeable salesman to work with! Central GMC was a great dealer to purchase from. Thanks again!

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

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

?????????? 5/5 ? Outstanding Experience from Start to Finish! I recently purchased a Hummer from GMC and had the absolute best experience I've ever had at a car dealership. Jacob M. was incredible to work with?professional, friendly, and genuinely dedicated to making the process smooth and enjoyable. From the moment I arrived, Jacob made me feel welcome and informed. He answered all of my questions, took the time to explain everything about the vehicle, and never once made me feel pressured. His knowledge and honesty were a breath of fresh air. I also want to give a huge shout-out to the entire team?from sales to financing. Everyone I worked with was courteous, efficient, and made me feel like a valued customer. They helped me pick out the perfect vehicle and made the financing process simple and transparent. If you?re looking for a top-notch dealership experience, I highly recommend stopping by and asking for Jacob M. and his team. They made this Hummer purchase one to remember!

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

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

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.
