Used GMC cars for sale near Barnstable, MA

Have brought our vehicles to this dealer for quite some time now. Always satisfied with the service and friendly staff. Would highly recommend them to others.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

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

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

We had to bring my car in for services. I was greeted by Michelle Martin !! She couldnt be more professional, helpful, and personable. She made the entire experience A1. She explained everything to me, including how to drive to the exit :) The gentlemen that gave me a courtesy ride to and from the garage were extremely helpful and appreciated.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

They diagnosed and replaced my AC condenser on my 2023 Toyota Hoghlander. The condenser is very susceptible to road hazard damage. The open grill does not provide any protection fron rocks and stones kicked up by vehicles in front of you.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

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.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Sean and Derek couldn't have been more considerate or helpful. Their reponse time and helpfulness were extraordinary. Sean made arrangements for Mike to meet us at the ferry, which saved us 3 hours of driving time! We have dealt with many new car purchases and never had service such as that. All three men were a pleasure to deal with!

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

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

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

No pressure sales, prices were on all vehicles in the lot, great buying experience. I found it easy dealing with the owners directly. Would definitely buy from them again.

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

Great service, great price. I have always been satisfied.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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 have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.

This truck is great if your not trying to haul 10k lbs. For every day use it's great on gas and I fit everything I need in the bed.

Cory is very courteous and very knowledgeable. Enjoyed my interaction with him. Would recommend him to my friends. Thank you Sullivan Brothers. Great people here

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

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.

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.

I would like to say big Thankyou , The nice people of colonial Ford and especially Brendan smith for making my transactions simple , fast and efficient

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.

We recently took our Service vehicle off Island as it needed some work and we were getting nowhere with service on Nantucket. Sarah and staff were able to get it fixed within 36hrs. We are hoping to start a new working relationship where we can rely and depend on quick service to our fleet of vehicles. Thank you!

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.
