Used GMC Sierra 2500 trucks for sale near Blue Hills, CT under $1,000,000

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

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.

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

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.

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 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.

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 worked with Steve Cortez and had such an amazing experience. He was super down to earth, worked with me to find a car that fit my budget, and was able to get a piece of the interior of the car fixed at no out of pocket expense to me.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

What a great dealership the people are fantastic super knowledgeable and helpful I’ve purchased 2 cars from them so far and go back for service all the time on my vehicles! Wow what a team definitely recommend this place to anyone who looking a car or looking to get their car service!!

Has everything we never knew we needed. Reliable and heavy duty. The bed is so convenient and we didn't have to chose between any options, this truck has it all.

This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

Found the specific, rare car for which i was searching. It was at Blasius pre owned. I had never heard of them so I took the trip from NY to see the car. The car was as advertised and I bought the car. 3 days later I went back and took delivery. Every part of the transaction was great. From the moment I walked in I was treated respectfully and everyone there is so pleasant. There were no games/nonsense just a straight, easy deal. No upsells, no hidden fees, it could not have gone smoother. I buy lots of cars and highly recommend Blasius. Special thanks to Adam Betancourt the salesman and Bobby Fernandez the GM for making this such a great experience.

Personnel at this dealer were very responsive and followed up with me until I decided to buy a vehicle from another source (pricing related).

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.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

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.

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.

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. ,

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

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Very good service. I was very pleased. The representative wrote an extended report of the service that was done. I would recommend them if you need service.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

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

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!
