Used GMC Sierra 2500 trucks for sale near Onset, MA under $100,000

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

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.

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.

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.

I worked with Amy. She was very notable and was able to answer all my questions.

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.

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

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.

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.

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!

No presure from the staff the experience was great, we have bought many vechicles here and will continue !

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.

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

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.

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

The service was fast and the staff is super friendly, it was a great experience.

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

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Finally an no pressure car buying experience! I like to get a new or new to me used vehicle but like many customers, kind of dread the whole experience of “dealing with the sales people”. I don’t like the whole drawing boxes, asking what I want my payment to be and let me go talk to my sales manager… AGAIN! I dealt with Josh and to be fair I knew what I was going in for so unless you have a day to kill on a car lot, do your homework prior to going to the dealership. When I got to McGee Josh greeted us and had the cars I wanted to look at ready to go for a test drive. There was a good demeanor with Josh and it was easy to work with him. Deal was made that day (Saturday) and I picked my vehicle up Monday with tags, title, registration and inspection sticker by 10am! By far this has been the best car buying experience I’ve had for a car that I really love. Thanks Josh and Joel at McGee!!!

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

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!

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

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

I was happy that buying a truck from here was an easy process. Everyone was welcoming and friendly.. I recommend this place 100%.The manager and his colleagues were so kind, professional and understanding.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Keith in the service department was great. Dropped off my truck, explained what was going on and kept me informed of what they were doing to fix it. Finished it earlier than thought went over what they did and his explanation was great! Would recommend you guys to everyone! Thank you, Paul
