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

?????????? 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!

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.

Working with Dave for our purchase was great! And at delivery he made sure I was comfortable with all the features before I left right down to making sure my nav was up and running so I’d be safely on my way!

I bought a hard-to-find truck remotely. Joel Picchi made the sale easy, answering all my questions, and helping navigate the challenges of an out-of state purchase. It ended up being one of the smoothest purchases ever! Thanks to the team for getting this awesome vehicle delivered to my home in central Maine!

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

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

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

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.

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.

I had a great experience at Central GMC of Norwood thanks to Jake. He went above and beyond to help me with my truck purchase and even took the extra time to help me empty out my trade-in. Jake was professional, friendly, and made the whole process smooth and stress-free. I highly recommend asking for Jake if you’re looking to buy a vehicle — he’ll take good care of you!

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

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!

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.

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!
