Used GMC cars for sale near Onset, MA

Definitely worthy of your consideration to see Manny Williams I had done my homework on comparing other dealerships to compare like vehicles in price, size and driving experience. He will work with you patiently answering all your concerns of comparisons and pricing.

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

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.

Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

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

I recently purchased a certified used Audi from Tracy Audi and the process was as smooth and easy as possible. Aside from photos, I never saw the car until I took possession of it but the car was described accurately and in great condition. In addition the salesman, Steve T. was very accommodating and made the purchasing process a walk in the park. I will definitely remember them for future auto purchases.

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Experience was great—came in, drove the car we were interested in and completed the sale in a couple of hours. People were super helpful and friendly.

I love the Yukon. It needs a few censors changed out but it drives so smooth. Very glad we made the choice to purchase it

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 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.

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

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

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.

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.

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

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

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

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.

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!

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

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

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!

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

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

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

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!

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Mike Maynard and John Finlay as well as Jack and Matt took great care of me when I purchaser my 2025 Land Cruiser. I would recommend them as well as the Land Cruiser, happy with all aspects.

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.

I bought a '17 Toyota Tacoma from Brian Olson back in November. In the past I have always had awful experiences with car dealers and sales people. They had taken advantage of my fiance and I , talking about prices and payments before we even saw the car physically. Then we had gone to route 44 Toyota and dealt with Brian. First thing he did was show us our options before talking about money. He took us on a test drive and was just all around awesome and informative. I trusted what he was telling us. He was amazing and I will never buy another car from anyone else. We left the lot feeling good about our decision. Rather than line his pockets with commission he got us the best possible deal. He truly cares about the customer and what works for them and not himself. I would definitely recommend Brian Olson at route 44 Toyota to anyone that's looking to get into a new/used car. Absolutely amazing. Definitely didn't disappoint.

I love my 2018 GMC Acadia just wished windows were tinted and had a tv for kids and grandkids overall I have had this truck for 2 years and I Love it and use it for family drives cuz of how much room it has I have even used it for work meetings and we all travel to the meeting together .

great styling and interior. nice features and acceptable performance. overall my Denali is a superior product to similar vehicles. I would recommend this GMC Acadia.

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

Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .
