Used GMC trucks for sale near Bethany, CT

We are happy with the staff and clean environment. Lucas and Rob was really helpful with the purchase.

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!

I had an outstanding experience purchasing my Cadillac Lyriq from Blasius Cadillac. Despite having researched the vehicle extensively through YouTube videos, sales representative Rich Noble took the time to thoroughly explain every detail during my test drive, ensuring I fully understood all the features. When I arrived late due to travel delays from Boston and a previous dealership appointment, the team was incredibly accommodating and flexible with my schedule. The pricing process was refreshingly transparent—we negotiated the complete out-the-door price entirely through email with no hidden fees or last-minute surprises. Most impressively, they coordinated with the Massachusetts RMV and delivered my vehicle directly to my home with plates and registration paperwork already completed, saving me an additional trip back to the dealership. Blasius Cadillac demonstrated professionalism, transparency, and genuine customer care throughout the entire process. Highly recommended!

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. :)

This was first time buying a car at a dealership. I like Toyota and my mother recommended Greentree Toyota in Danbury because she had bought a Camry there ten years ago. My salesman was Mike Shakro and he was very good. I was buying a used car and I gave him a price range I wanted to stay within and I told him 2016 or newer. He showed me three cars but I liked the Nissan Sentra 2016 with 20k miles on it. Max Tananbaum, one of the managers, came out to visit us and gave us below the list price. We got a Rust Proof undercarriage protection that allows us to get an additional $500 dollars if I ever trade in the car in the future. Jose Cordero was very helpful with a three year warranty that included towing and car rentals in case the car ever needed to be fixed. I was thoroughly pleased with my experience. It didn't take that long considering how busy they were and Mike the salesman even help me return my rental car by suggesting they were only a quarter mile down the road from the dealer. They have made me a loyal customer from now on.

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.

Todd was our salesman. Our car buying experience was handled very professionally and with great care. Todd did not rush us through the process. He was very prompt while we tested the vehicles. His manager closed the deal and showed the same level of care. We will definitely return with our family on future car purchases.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Love her the best sales person ever. Very informative and very helpful. I would recommend her to everyone

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.

Had a great experience buying a used car here. Everyone I dealt with was friendly and knowledgeable. I never felt pressured, and being a single female, that was important to me. They gave me a fair price on my trade-in, and their cars are reasonably priced. Will Anderson was a terrific sales guy, and Jill and Matt guided me through all the paperwork. *Highly* recommend this dealership!

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!

What a pleasure to deal with salesman manager number one Would definitely buy another car from them in the future

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

Had a great experience buying my truck with monaco!!! Would definitely recommend to anyone who is looking for a vehicle to take a look at monaco glastonbury!!

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Amazing experience with both the salesman (Vic) and finance department. Vic was amazing. Courteous, helpful, absolutely no pressure or “up-sales”. Entire process took less than three hours. Highly recommend. Seamless experience. Thanks again Vic.

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

Worked with Steve, didn't end up buying but he was super nice and upfront with us. A much better experience than some of the dealers we talked to on this journey.

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.

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.

We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Volvo is a great car! However, I enjoy interacting with the people who work for Gengras and find them not only professional but extremely nice and very helpful! I wouldn’t go anywhere else!!!

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 !

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 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 have bought from Peter a few times over the years with great results! He is a true professional and I trust his expertise completely. He is the first person I go to with any auto needs and he always has the answers. Wholeheartedly recommend!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

It was a pleasure to deal with Zach, Patrick and Mike. The car was as Zach described, and I am very happy with it. The purchase was made easy by these guys and they were very accommodating:)

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Incredible buying experience from Wallingford Auto Park. Joe Scott was great to work with and I really liked the no pressure way of doing business! They had exactly the vehicle I was looking for, handled everything onsite and drove out the same day with my new SUV. Highly recommend buying from this dealership!!!

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.

This is my second time leading with Blasius Kia and both experiences have left me feeling extremely satisfied! Everyone I worked with was helpful and listened to what I was looking for and when it came time to paperwork and making the transaction, it was flawless. Would gladly continue to drive an hour to this dealer again for all my car needs

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.

Very pleasant experience! Family has purchased vehicles from Terryville Chevrolet for a very long time and never had any problems. They were very helpful, very professional, and extremely kind. Will buy another.

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.
