Used GMC Sierra 2500 Denali for sale near Naugatuck, CT

Thank You Norbit and Thank Steve for crunching those numbers for making it happen. Nor you wanted me in that Cadillac Escalade and I am. Once again thank you J&M Automotive for looking for me.

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

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.

Go see Luis at Blasius South. He was attentive and very easy to work with. The whole process was perfect start to finish. Everyone there was helpful and very knowledgeable!!

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!

Britney, Doug, and Aaron all had a hand in my buying process. They were all very accommodating, informative, patient & professional. They made the experience of buying my first brand new car, seamless.

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 found a Ford F250 that had the options I was looking for on cars.com that Blasius of Middletown had in stock. Contacted Edwin (salesman) to confirm truck was still there and set up an appointment. The truck was detailed and ready to go when I arrived after a 3 hour drive to the dealership. I liked the truck, so I made the purchase. We negotiated a little on my trade and came to a deal we could both agree to. Overall had a smooth transaction.

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.

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.

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!

Carmen was GREAT! Celine got us up on the road quick and we drove a loooong way. Thanks guys, love our Jeep! The facility is amazing!

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

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

My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼

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.

Great experience all around, gave me a a fair trade in valve, would highly recommend.

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.

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

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

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!!

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

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!!

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Mike and Chris were awesome. Chris in finance was extremely helpful. Would definitely recommend. Great service department also.

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!

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!

ask for Heidie, she goes above and beyond to get you in a new car !! whole process was fast and smooth like butter. loved it

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.
