Used GMC Sierra 2500 trucks for sale near Weweantic, MA

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.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Joseph Licciardi was very helpful with the whole process and was graceful enough to give me his favorite pen!! Wouldn?t hesitate to visit this dealership 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.

Brandon was very helpful with the information I needed to purchase my new car. He answered all my questions on my purchase, Brandon couldn't have been any nicer I recommend him highly

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.

The folks at O?Hara are unfailingly polite, service is always done right the first time and at a fair price. Always a pleasant experience getting my Jeeps serviced.

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.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

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.

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.

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!

We love this place,we highly recommend very friendly stuff!!

I was treated real well he was kind an was very helpful I would return an purchase from there again

Clean Facility, Quick Response and Hard working staff, and Stress free service and sales

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.

They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.

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!

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.

Great service very friendly and professional. No stress with test driving or even "talking numbers" it was a great experience and will go back there again.

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!

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!

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.

Recommend Isaiah, good salesman, took good care of us with our purchase. 2023 Cadillac XT5

Went to have my truck serviced and staff was friendly, the facility was clean and the service was done quickly and correctly. Would recommend to my family and friends.

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