Used GMC cars for sale near Onset, MA

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've had mine for 4 years 2016 SLT ,traded my wife's Hyundai Santa Fe for a caddy srx which I drive as well as a 2018 GMC 1500. The Acadia has been super reliable .knock on wood.. just basic maintenance

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

From the first moment to the last everyone was great, everyone had a great personality, everyone was very helpful, but this process of buying my first new vehicle went smooth sailing with the help of Carlos Moniz and Duarte Arruda I can?t thank them enough. I highly recommend the dealership

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.

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.

Got it for the ride ,comfort,great gas mileage on trips,can do a 750 mile trip and not be warn out from the ride.Can carry a lot of stuff .All the different options are great

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.

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.....

Impeccable service and attitude! My car was serviced quickly, at a good price, and everyone was very cordial as always. I have been coming to Colonial South Chevrolet for a few years now, with excellent experiences throughout. Thank you!

traded in my 2013 buick enclave for this 2023 gmc acadia. i think the ride is a little better , fuel mileage is better over all comfort is great. Ed at Patriot Buick GMC was great in explaining all its features.

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 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!

I have been very happy with McGee Toyota. Tuesday I hade my 5000 mile oil change and a front end break job. The customer service was great. The maintenance area is the cleanest I’ve ever seen. The waiting area was spacious and comfortable. Great staff, great communications, highly recommended.

Recently had my 2024 Camry in for an oil change. AJ did a great job communicating the process and status of my vehicle. Making sure everything went seamlessly After having had a bad experience at another Toyota dealership, I brought my business to McGee. I have worked with AJ from day one at McGee. He has always been professional and courteous.

I bought my gmc canyon used with 29,300 miles on the odometer. It has the 2.8 ltr I-4 turbo diesel engine. I'm towing a 5,000 lb travel coach. First thousand miles was today. The small engine gets for me astounding fuel milage. Towing the coach i averaged 22. 8 mpg on a trip to the Eastern Sierras. 368 ft lbs of torque is more than enough to haul the trailer to 10,000 + ft elevation. Just be patient and use the torque to tow up a mountain. The fit and finish is excellent, the blue metallic paint turns heads. After 3 yrs a good waxing had it looking showroom new. This is my first gmc ever. If it holds up and runs 300,000 miles like the sales rep stated it's capable of doing. I'll let you know. The one down side is the emissions on the engine can cause reliability issues. Advice i found on a forum says use a good quality injection cleaner in every fill up . Every fill up for the life of the truck. They are capable 300,000 and higher if we'll cared for.

I brought my Equinox in for routine maintenance. The service was prompt and efficient. The waiting area was comfortable and well lit.

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.

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.

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!

Best place I have ever been to. They turn every rock to make it happen for you.

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?

Experienced, knowledgeable, customer oriented w a personable platform affording more confidence as a prospective customer!

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Great service and friendly staff. Timely and excellent work! I will be happy to recommend to others!

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

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

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

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!

GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!

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.

Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

My husband and I were in search of a used Ford Fusion Hybrid, since our other one was slowly dying of old age (13 yrs./213,000 miles) but had been very reliable for many years. We were thrilled when we discovered a 2018 Fusion Hybrid right down the road in Easton MA at a long established and locally trusted dealership (South Easton Motor Sales). Derek was a pleasure to work with and was VERY thorough in preparing the vehicle and VERY accommodating with both of our work schedules to arrange the day & time for us to pick up the vehicle. Can't ask for any more than that in a dealership, and the car is primo and was reasonably priced! Quality, value, honesty & respect...HIGHLY recommend this dealership!! Colleen V. (Norton MA)

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 .
