Used GMC Sierra 2500 trucks for sale near Wallingford, CT

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.

Just purchased a 2016 Mazda Cx9 from Wiz,my salesman Jeff was very professional throughout the process no multiple hours haggling back and forth over prices Scarlet in finance was terrific,would definitely recommend Wiz auto for your next preowned purchase

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!

A full service Ford truck shop. They take good care of my 2022 F 450.

Delightful & pleasant experience with Vincent and Ed at Mercedes of Fairfield. No other Mercedes dealership compares to this service organization.

My guy Victor had me in and out in no time excellent experience! Go there

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 service, very professional, did take long in and out quick.price very reasonable, very nice people, everything was excellent and all problems that were found were explained

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!

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

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.

I recommend this dealer, for their good service, I am very satisfied.They answered all my questions.

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.

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. 👌🏼

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

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Luis was a prepared, kind, and cordial associate who I had the pleasure of working with. After some honest negotiation and a little bit of elbow grease, he got me to my number. My Dodge Hornet has been great! He made buying this car a breeze and was very responsive over email as a pre-vetting process.

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!

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!!

I got a good deal on the car. Tyler was great to work with. If there was one thing to complain about, it was the time it took to work things out. I was there for four hours, just wish we could’ve cut down on the time.

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.

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!

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!!

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.

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.

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.

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