New and used 2025 GMC Sierra 2500 trucks for sale near South Duxbury, MA

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

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

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.

?????????? 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!

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

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.

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.

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.

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

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

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.

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

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.

Everyone in the Service Department was professional, knowledgeable, friendly & very punctual!! Great service & a friendly environment!
