Used GMC cars for sale near Groton Long Point, CT

An amazing experience with the service department and collision center at this dealership after my car was damaged by a fallen tree. The process right from the beginning was flawless. Getting the car to the dealership, getting the rental car, the time it took to get the parts and do the repairs was quicker than expected. The ease and efficiency of the repairs and the quality and timeliness makes Gates GMC. Jamie Laskow and his team get 4 stars from me! I will definitely recommend your dealership in the future.

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

My initial dealership experience was with Scranton. While I can't compare it to others, why look elsewhere when it's already perfect here?

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!

The team at Valenti Toyota is personable, professional, knowledgeable and experienced. They listened to what we were interested in, and they worked with us throughout the purchasing process. Sales consultant Steve Macomber was especially helpful in assuring that we felt comfortable and informed from the initial contact until we drove away in our 2016 Camry. He displayed a thorough understanding of both the vehicles and the process. Sales manager Rocky Sposato and business manager Scott Morrow were direct, honest and straightforward. Overall, we were treated as a member of the Valenti Toyota family from the moment we walked in the door.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

I had routine maintenance done on my Encore. The service as usual was excellent. Very friendly and professional service staff. They are a pleasure to work 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.

A quality dealership in all respects. Knowledgable personel in sales, finance, parts and service. We?ve been dealing with this dealership for nearly a decade since moving to RI. We have either purchased or traded in several vehicles with the promised hassle free process. Our vehicles are always serviced/repaired right the first time at a reasonable cost.

I had a wonderful experience buying a brand new jeep with the help of Bruce. He was the perfect amount of friendly, honest and informative without being too pushy or in-your-face like you normally would expect from salesmen. Bruce spent basically the entire day with us, patiently answering any questions we had and made us feel comfortable and confident with our decision. We were able to test drive a couple cars of interest before finding the perfect fit for me. The following days after I brought home the car, Bruce contacted me to ask how the car was driving and wanted to ensure that I made the right decision. 10/10 would recommend him if you are looking to buy a new car!! Thank you Bruce!

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.

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.

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.

Amazing experience from start to finish. It was well worth the 180-mile trip. I've purchased 8 cars in my life, and this was by far the best experience I've ever had. Completely transparent and honest. THANK U GUYS!!! Will be back for my next vehicle for sure!

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

They turned what is normally for me a nightmare into a dream! I can’t say enough about Brustolon and their whole team! They explained everything to me in extreme detail. Made sure I understood everything. They really had my best interest in mind especially when it came to the financing. They got me an unbelievable rate. My credit union couldn’t even beat it. These guys are great i’ll never buy a car anywhere else!!! Thanks again Joe and Chris!!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

It was a pleasure working with Chris. He was on point and very professional throughout the entire process. Would highly recommend him and Shoreline

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 recently had an outstanding experience purchasing my 2024 GMC Sierra AT4 at Gates GMC in Windham, CT. From start to finish, the team at Gates exhibited clear communication and professionalism, making the process seamless and stress-free. What stood out the most was the transparency and honesty in every interaction, with no hidden agendas or surprises. I felt valued and understood, and they made sure all my questions were answered. I highly recommend Gates GMC for anyone looking for a reliable and customer-focused dealership. Thank you for an exceptional experience!

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 .

Great people sure of the lady ZOE she?s very nice when I met her I knew I was going to meet nice female the vehicle I got was. Nice

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.

Service was excellent, very helpful salesperson (Matt Bouchard) and finance person. I was surprised how much the salesperson helped, contacting insurance and even connecting my cell phone to car system:screen for me.

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.

It?s a pleasure buying experience. The sell consultant and the dealer are all friendly, helpful and considerate. The shopping environment is clean. According to the introduction, the after-service is good (because I just buy a new car).

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.

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!

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!

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.....

Purchased a new car for my Grandmother here. I have never had anything close to the experience i got here. From the initial hello when i walked thru the door, to the final handshake, these folks are top notch! I personally worked in the car business for over 10 years and have yet to be treated better in any dealership. They will continue to have my business for years to come.

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

I ended up with the car I need. Edgar was very helpful in helping me find the Subaru legacy that I needed. A little work needs to be done, I know about the window being off track, now I'm shaking as if I have a sunken ball joint. I was told the window would be taken care of, I'm really hoping this is too. I will be purchasing a second vehicle with my tax refund, which would make my third purchase. I would rate Bob valenti an 8.5 out of ten and my salesman a 9.5 out of ten. I've never purchased a car from a dealership more than once anywhere else and for good reason!

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.
