Used GMC cars for sale near Onset, MA

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 knew what kind of vehicle I was looking for and SEM had just what I wanted. They were very simplistic in their sales with no high pressure or fast talking. I either wanted the vehicle or I didn't. They answered my questions and helped me fill out the paperwork. It took a few days for the car to be ready as they had to give it their inspections and complete the paperwork, but it was ready when they said it would be. Since I was buying a used vehicle, I decided to purchase the warranty and am I glad I did. As with every older vehicle there can be maintenance problems, but SEM was extremely helpful and conscientious in making sure my vehicle was in proper working order. They were happy to listen to my concerns and help me figure out what exactly was wrong and they fixed it far better than I could have expected. Their sales and customer service are exemplary. My son needs a new car and I will be returning to SEM as I know I can expect the best sales and service. Thank you, SEM, for having the right vehicle and providing me with a vehicle that was safe and suited my needs.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

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

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

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!!!

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Anthony Miranda and Eric are the best! They were very helpful with the Jeep and I am very happy with my new car purchase, thank you!

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

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

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

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!

I just purchased it new. Love it. the interior, the way it rides. Its a great bang for the dollar. A must own. I wish the MPG was a little better

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.

I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

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

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

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.

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.

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!

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!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

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.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Great place for service and hassle-free purchase, Service Dept is great my truck is always done on time.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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

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.
