New and used 2025 GMC Sierra 1500 trucks for sale near Sherman, CT

The Ingersoll employees provide excellent and friendly service as always whenever I go there for service or to purchase a new car. I highly recommend the dealership.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

The best ever service knowledgeable very efficient with explanations

Always reliable and outstanding customer service. Waiting area well stocked and comfortable. Staff friendly and informative, attentive to details and future needs. Service department used modern diagnostic equipment that can be reviewed while waiting

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!

Love going to Colandrea I buy and service my vehicle here They are the best

Always great customer service. Excellent waiting area with fresh coffee and a good choice of goodies while you wait! I love the new computer system showing your car while you wait

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

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.

Amazing service team, tech kept vehicle clean and service Consultant kept me up to date on my needed services and repair, pricing is affordable and fair

Vinny at Sullivan's Northwest Hills was great to work with and to buy a car from. It was truly a good experience. He was very knowledgeable and let you lead the conversation. I will buy my next vehicle from Vinny the next time I need one.

My experience at Northwest Hills Chevrolet was exceptional. I was treated with the utmost kindness and respect, and accommodations for my special needs were made willingly, and in some cases, without my even needing to ask. My salesman, Phil Musmacker, made everything incredibly easy for me throughout the entire process (honorable mention goes to Brendan Elrick, who followed up on my initial request for info on the Equinox EV, and connected me with Phil). In addition, I never found any reason to question the pricing on the purchase order; everything was straightforward and exactly as I had been told, which is incredible considering my previous experiences with dealerships, where I had to fight to keep extras from being added to my order. Truly remarkable! I've already recommended Northwest Hills Chevy to a couple of friends! Thank you for a most wonderful experience (and I also really love my car)!

I walked in with something very specific in mind. Even though I didn?t get the car I built online Colandrea was able to offer me the next best possible thing. I?m picky but their associate read my mind and was attentive to what I wanted. I looked at just one car and fell in love with it. Took it for a test drive and made the deal. The longest part of the process was trying to see which of the approval offers best fit me. They fought to stay within my budget. They found me the lowest payment option possible. I was in an out of there in less than 3 hours and returned the next day for my vehicle. Painless!!! This is my NEW dealership! Thanks to Floyd and Dan!

We are happy with the staff and clean environment. Lucas and Rob was really helpful with the purchase.
