Used 2024 GMC Sierra 2500 trucks for sale near South Windsor, 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.

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.

very good . the pm's that werte compleated were checked off and not everey box was checked off like last time . it i see a box checked off and that service was not required or compleated i will go somplace other than your location. a good pm programhave has certain guidelines to fallow. the person compleating the pm's should not check of a pm that he did not comcomplete, and checked off after completion. i hav worked with vehicle pm programe in the U,S MARINES AND U.S Army and U.S Air Force . alos for the city of chicopee for 30 years. it was unacceptable and quite shocking when i picked up my truck to find all pm check boxed checked . this was not my last pm with you but the one befor. ,

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

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.

Edwin was great to work with from the beginning. He reached out shortly after I inquired about the car and scheduled a time the next day to take a test drive. They were able to complete the purchase that day so I could take the car home. Overall, both Edwin and their Finance department were easy to work with.

Vinny at Sullivan's Northwest Hills was great to work with and to buy a car from. It was truly a good experience. He was very knowledgeable and let you lead the conversation. I will buy my next vehicle from Vinny the next time I need one.

Service is always tops Sales department the best Would recommend to anyone looking for a new, used car or service. Blasius Chevrolet is, by far, the best dealership in Connecticut

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.

Great dealer. No hassle. In my new vehicle the same day. Smooth transaction. Very happy with whole experience.

It was a good experience. The lead sales man was a little on the rough side. But all was good.
