New and used 2025 GMC Sierra 1500 trucks for sale near Dover Plains, NY

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!

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.

I just purchased up a late model Pacifica. The transaction was professionally handled. There were no surprises. A hat tip to our salesman Julian and Ken in service, both customer focused. I particularly appreciate their followup communications. It does make a difference where and with whom you choose to do business.

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.

I needed a new battery for my car which was still under warranty. I called the dealership where I purchased it but unfortunately they couldn?t fit me in for three days. I called Hudson Buick and they told me to bring the car over, they drop me off at the mall for a little while came and picked me up on my car was done. Great experience.

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

Great, quick and friendly. Ethan and Steve make my experience enjoyable and seamless and helped me find the perfect car.

Number one GM dealership in the northeast. Pat Duke and Steve Vitiello are the best. This is my second truck from them in the last 18 months. I bought a certified 1500 Sierra SLT for my son last June and just bought my self the 2025 Sierra 3500 Denali ultimate DRW truck! This truck wasn’t in stock but Pat worked hard to find this truck for me with the specs I wanted and kept me posted about everything along the way, and made sure I got the most for my trade. When it came time to deliver he knew everything about the truck and made sure I did also. Steve is the best at what he does, I can’t thank him enough! Thanks guys this new truck is amazing I love it!

Great experience and service!! Prior to pickup everything was explained and verified in order to have a seamless delivery experience. Sharon was great at going over everything and Mike took it home with no hiccups. Definitely great customer service and experience!! Would recommend and buy another vehicle!

I bought two cars from Mike Barrows. Mike's salesmanship goes unmatched. He did not pressure us at any point and was always willing to do his best on a price for us. The transaction was quick, easy and smooth. Just to top it all off Mike donates $50 dollars for every car he sells to united for the troops and having two grandparents that served this really blew me away. Thanks Big Mike!

We just bought our 2026 Chevy Traverse RS and couldn’t be happier! From the very beginning, Whitney Johnson was so helpful in setting up our appointment and making sure we were on the right track to find the perfect car for our family. Katrina helped us put together our very first deal and made everything feel so simple and stress-free. Tyler Hallenbeck, our salesperson, was absolutely wonderful… he was kind, patient, funny, and really took the time to answer every question we had. And Steve in finance made the final steps smooth and easy, which we really appreciated. The whole team made what could have been a stressful process such an enjoyable and exciting experience. We’re so thankful for all of their help and love our new Traverse RS already! Highly recommend this dealership and this amazing team!

Andrew did a wonderful job when selling us our 2026 Chevy Equinox..He was very friendly and informative

Romeo took good care of me. Ashley made sure that I was very comfortable in the vehicle before she let me drive it from the lot. Many thanks to Steve as well.

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

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

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

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