Used GMC Sierra 1500 trucks for sale near Thomaston, CT

REBECCA WAS AWESOME! friendly, knowledgeable, personable, listened to needs and provided helpful insight and many choices. Purchasing with Angel was a great experience. He was no pressure and very knowledgeable and accommodating.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I got a good deal on the car. Tyler was great to work with. If there was one thing to complain about, it was the time it took to work things out. I was there for four hours, just wish we could’ve cut down on the time.

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!

So far so good I have not yet picked up the vehicle but so far everything is as they have said it would be

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

Dylan was a very nice respectful young man who made my experience at highline car connections a very nice and enjoyable one leading me to purchase the car I was hot for.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

I've bought 4 vehicles from this dealership as a return customer die the the (CPR) - Courtesy - Respect - Professionalism I live in Delaware and make the journey for these three requirements for me to purchase. Ask for Lou 😉

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Veronica was amazing!! She was patient and got us where we needed to be to drive away with a new car!! Would highly recommend asking for her help if you’re ever in town looking for a new car!!

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!

Pete P. was great! Pete helped us purchase certified preowned Toyota Highlander! Great customer service from start to finish. Casey handled the sale paperwork, seamless. It was a pleasure to do business with Greentree Toyota. The entire staff receptionist to sales exceptional! Be sure you ask for Pete.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

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.

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.

Went to Moncaco Ford for service - brake inspection. Mickki did great job at get my Escape SUV serviced. Needed rear brakes.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Working with Ray to close the deal was amazing. He is very familiar with the vehicles and options available to the customers. He knows the material and how to get his customers to their end goal. Thank you Ray for helping us drive away with our new 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.

Bought a 2015 Dodge Challenger with 5800 miles - great price compared with what the same car is going for today with 40K / 50K more miles. Process was easy. All my friends love the cards and strangers give me compliments. My only complaint was these cars go through an inspection where all problems are fixed. I bought the car in February and by the Summer when I finally turned on the A/C, it did not work. When I went to the repaair shop I was told it would cost me 41000.00 dollars as the hose was broken dehind the instrument panel. In my opinion this should have been caught by CARMAX and fixed before I picked up the car. Otherwise very happy - no problems other than that to date. CARMAX - please fix my A/C??????

I had reached out to check out a vehicle they had in stock, and everyone there could not have been nicer, or easier to work with. Katie, Sam and Brian were very friendly, helpful and even though it wasn't the right car for my needs, they couldn't have been nicer.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

The sales staff and the management with above and beyond their duties to make sure that my new vehicle purchase went very smooth. Will definitely come back.

Great no stress car buying experience from the beginning to end. Happy with my experience.

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!

This place is great. I just drive the car. I fell in love with the car and I took the car off the lawn. They’re amazing.Go see Alexa and frank

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

I recently leased my second Volvo from Gengras in North Haven. What a great experience I had! From being greeted as soon as I arrived to driving out with a beautiful new car - everyone was professional and willing to make sure I had a positive experience. Brian and Corey worked hard to get me into the car I wanted for the price I wanted. Manny made sure I understood all the paperwork and helped me get the best coverage for my new vehicle. Stacey was amazing - explaining all the features of the car and helping me get hooked up to my new voice activated system! I wouldn't go anywhere else to buy a Volvo.

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

Easy to work with, great communication and response. Definitely recommend when shopping for new vehicle

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

I am Very happy with the work they did and highly recommend them. Very professional.

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.

Very thorough and helpful. They answered all my questions promptly and thoughtfully. I was able to obtain the car I was looking for with unique details specific to my needs. I would recommend.

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.
