Used GMC cars for sale near Cornwall, CT

On Saturday, June 7, my daughter and I had an outstanding experience at XXX Chevrolet. While my initial intent was simply to support her in purchasing her first vehicle, I ended up trading in my own car and driving away in a brand-new 2026 Equinox — while she purchased a 2025 Colorado. Both vehicles impressed us during the test drive. The safety features, interior design, storage space, and overall aesthetics sealed the deal for both of us. While comfort and safety were top priorities, what truly set this experience apart was the exceptional service we received. Steven connected us with Brian, an outstanding sales specialist who was both highly knowledgeable and incredibly personable. He built immediate rapport, listened carefully to our needs, and guided us to the right vehicles without any pressure. The process was smooth and efficient — we were both driving off the lot the same day! The dealership itself was clean, welcoming, and even treated us to a delicious lunch during our visit — a thoughtful touch that made the day feel even more special. I’ve purchased several vehicles over the years, but nothing compares to the level of service we received from Steven and Brian. I highly recommend them to anyone looking for a car-buying experience that’s professional, honest, and genuinely enjoyable. Judi and Jackie T.

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

Thank You Norbit and Thank Steve for crunching those numbers for making it happen. Nor you wanted me in that Cadillac Escalade and I am. Once again thank you J&M Automotive for looking for me.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Well I came 31/2 hours to see a car and it’s gone yesterday I wanted it I was buying it because i recked mine i wanted the same thing

Excellent service! Quick and easy process. Very professional and friendly.

I had an excellent experience with having my car repaired at Ingersoll Chevy. My car was diagnosed and repaired as promised. The whole service department was friendly and knowledgeable.

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.

Had a fantastic experience at blasius, this is my second vehicle I’ve purchased from them. Wayne was so helpful and made the entire process so special and easy for me. The finance manager Marissa was also such a sweetheart and explained everything to me.

Extremely nice staff, very professional team players from service desk to the shop. A very clean and safely run facility. Waiting area was comfortable. Service was done in a reasonable time. Service prices appear to be fair. Will definitely continue with my service here, also would consider a purchase from them in the future.

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.

I just purchased my first ever brand new car from here. I traded in my well loved used car. Mike was super helpful and kept me at ease through out the whole experience. Answered every question I had. Ellie was great at helping me get a good loan and rate. Highly recommend this dealership. ~Amy

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

Justin at Ingersoll was wonderful to deal with, he is knowledgable and caring. Dom the manager came out to introduce himself and welcome us. Ellie went out of her way for us re our new registration.

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!

Thorough and courteous. Great customer service. Oil changed and issue checked out and repaired.

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.

I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.

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

Jason and everyone at good guys are doing it right! Very fair and transparent. They deserve your business.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

So far the car is going great. We have had no problems driving everywhere and so far had no need for services. It is a great care for me and my husband,

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

We have a long standing relationship with Mike Iacino at Acura of Avon. He makes it so easy to purchase a new vehicle. He knows his client and knows what that client would be happy with. Of course, we love the product so selling us a new car is easy! All the other salespeople, including the manager, are always warm and welcoming . And, you know that the Service Department will stand tall as well. I can't forget to mention Nissa Johnson in the Finance office. She is really the very best!

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

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!
