I dealt with Rich Noble and he was excellent. I am very satisfied with the purchase. I would recommend Rich or Blasius to anyone looking for a new car.
Great Truck
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.

Good service
We dropped in without an appointment and worked with Kent to test drive several cars. He was very knowledgeable and helpful. We appreciated how much he was hustling to serve several customers. We really liked that he didn’t hard sell us and was focused on understanding what we were looking for.
Best truck I have owned
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.

Very friendly and personable.
We were blown away at just how easy of a process it was to buy our car from this dealership. Everyone was absolutely fantastic. That includes Colleen, Matt, Kyle, Joe, Peter, and the rest. We would love to deal with them again. We are VERY pleased with the car, the service, and the general attitude of everyone there. I highly recommend them.
2020 GMC 2500 AT4
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.

Great Service Department
In maintaining our 2020 Buick Enclave, we have used Buick GMC Watertown Ct, since our purchase in September 2019 and have always received the best on time, reliable service and friendly customer service on our visits. The staff that reviews what service I am requesting will always review for possible upcoming recommendations of service as well. The cost and approximate time of completion has always been spot on.

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

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

Most convenient options on any vehicle I've owned.
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.

A Beast when it comes to hauling!
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.

On Saturday, June 7, my daughter and I had an outstanding
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.

Wallingford Auto Park: Best Place To it A Car
Excellent dealership. I worked with Phil and bought a Nissan Rogue. Phil is the best salesman I have worked with. He made the whole buying experience so easy and stress free. I’m so happy with my purchase. My entire experience was top notch. Thank you Joe and Marcelo also. You guys are great!!

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!
