Used GMC Sierra 2500 trucks for sale near Suffield, CT

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!

I had an awesome experience with these folks. Friendly, informative, answered all of my questions. Jonathon was a joy to work with, as was Jeff. I have told all of my family what a great, stress free experience I had. If I ever have the need again it will be my go to place!

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.

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.

Tim was an exceptional salesman he genuinely cared about our experience buying a new car. Took extra time to help with questions and setting up account . Answered all calls quickly. Took time to teach car systems not once but twice. Didn?t feel pressured Would def buy from dealership again.

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.

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 bought three cars from AutoCare in the last 5 years. The owner Frank is a no nonsense car guy. He won't waste my time if I don't waste his. That is to say; when I go to his dealership with the INTENT to purchase a vehicle, he goes out of his way to make it happen. Never an issue with either vehicle I've purchased from him.

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

Thorough and courteous. Great customer service. Oil changed and issue checked out and repaired.

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!

Our salesman Colin was extremely helpful making our buying experience seamless and simple answering all of our questions

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.

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.

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.

Super clean and friendly dealership paper work went smooth and fast got the car I been looking for for the best deal definitely would recommend to friends and family

First , I bought gas 6.0 , the diesels are great if you have serious towing needs. You just need to realize no matter how well you maintain a diesel it will at some point have an expensive repair. I've had my truck about 12 years. Regular maintenance , a few batteries , couple sets of tires and a MAF sensor. I tow a couple different trailers and the heaviest is less than 10k loaded. Towing , zero issues , no band aids , no overloads , no equalizing hitch , no sway control. Simply not needed. Drives amazing, stops great, Roughly 10 to 12 MPG towing. Unloaded driving at 60 / 65 on cruise solid 15 to 16 MPG. Yes , it won't pul the hills like a diesel but thats a small price to pay for an absolutely amazing truck. I want a new truck in the worst way but just can't part with this truck. A very good truck if you find a clean well maintained one.
