Used GMC Sierra 2500 trucks for sale near Sagamore, MA under $899,990

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

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

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

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

The fact that they only sell these small Trucks clearly makes them better at buying them which results in a better Truck to buy, they have been there like 20 years so they will always be there when you need them, My family has bought 2 Rangers and a Colorado over the past few years and they stand behind what they sell! When I need another Truck or any vehicle I know I can go there and I'm done.. Brad

Love the comfort and performance of this truck! So far it's meeting all of our expectations. Gas mileage has been great so far as well.

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've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

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

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

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

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

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.

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

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

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.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Manny was the consummate professional and took care of everything from A-Z. I am completely 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.

Great experience! The minute you walk in the door you call tell this is the place to do business Friendly people with no pressure. You feel like they just want to take care of you

I cannot say enough good things about Atlantic Subaru probably hands down the best dealership I’ve ever been too and I’ve had a lot of cars Lol. Very professional and fast every time I go I can’t believe how I’m in and out in less than a hour. Love all the service girls and how highly knowledgeable they are, so nice work and a huge thank you to you all!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Usually not a type of person to write reviews but after dealing with colonial Ford and Brendan smith and Dell Roderick i have to! The whole team went out of there way to get me approved on my dream truck to be able to provide for my family and i can’t Thank Brendan and Dell enough see these guys.
