Used GMC Sierra 2500 trucks for sale near Marlborough, CT under $100,000

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.

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.

Due to a national backorder of a part my truck took over 120 days to return. Gates GMC did inform me thru the process

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

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!

Champagne Motorcar provided a great car buying experience. They had a fair trade and a reasonable price for the used vehicle. Dealt with a gentlemen named Ernie, he was very professional and non-aggressive The whole transaction was clean, prompt, and worry-free. The 2015 Honda pilot I purchased had its blemishes which was too be expected, and all Ernie would say when I pointed something out was “Oh. no problem we will take care of that!” Not that I haven’t heard this before but they did take care of EVERYTHING, This vehicle looked brand new when they were done with it! I look forward to purchasing my next vehicle from Champaign Motors! Now I know where they got their name, they are the Sparkling Bubbly of EXCELLENCE!

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!

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!!!!!

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.

Your next car should be from Capitol Garage no matter if it is a new or like new used vehicle you are looking for. I sincerely recommend you to check up this dealer in person because you’ll never regret it afterwards. They do support you in get your next car regardless of financial situation. This was a decisive factor in got my like new car from Capitol Garage. Give them a call to set up your appointment or pass by to check on their awesome inventory in real time. Super nice cars all over!

Nothing but positive, seamless and professional. This dealership was not my first stop but it will be the only one I buy any future vehicles from.

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!!

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

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

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.

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.

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 have been dealing with Bolles Motors since 1987. I purchased 3 Jeeps from them -- a Laredo, Grand Cherokee, Patriot -- and I have leased my last 3, all Grand Cherokee Limited. They are a great dealership and their service is equally outstanding. Brian makes it a point to say hello and check in with me every time I visit the dealership. I have dealt with Barry Pinto several times (sales/leases) and Dan in service is top notch. I wouldn't deal with any other Jeep dealership.

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.

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.

Was contacted by Zach from Waterbury dealership. Right off the bat I felt like he understood my needs and wanted to work a fair deal for the sale of my truck. We got it done and myself into new Colorado. Staff was very helpful and patient. I would recommend this dealership team to anyone. Thanks!!

Really enjoyed this car buying experience. When the car started acting up they were all over it and fo t it to a Ford dealership for diagnostics. Literally refused to let them send the car back until they were satisfied that my car is tip top. Can't say enough about Dave in sales, Phil their awesome mechanic who advocated for me like it was his own car. Then the GM met with me to talk about the experience and stand behind the car if the same problem recurs. Jessica at the desk made a rough week much nicer. So pleased to work with Blasius of Middletown and will be a repeat customer for sure!!

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.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Edwin Ocasio was very professional and listened carefully to what I was looking to buy in a vehicle as well as my price range. As I test drove he answered all my questions in detail. After purchasing my Jeep Compass I noticed one issue that needed to be fixed. I brought vehicle in the next day & it was taken care of. Thank you Edwin for all your help. I I am very happy with my purchase.

Recently bought a used Lincoln from Blasius. Great experience! Ken McKay is a great guy. Took car of everything. Great car, great price, great experience. Wouldn't hesitate to go back. And thanks to Chris in finance as well. Another great job.

The salesman was great. No pressure and willing to negotiate. The finance guy was even better. Overall great experience buying a car.

Just bought a Colorado from Blasius Branford and impressed by the quality of vehicle, price and service. Joey Posa and Mike De’Angelo were great to work with—highly recommend

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.
