New and used 2025 GMC Terrain for sale near Barnum Island, NY

Rob Birchall and the team were great. Was towed in on a Saturday and they were able to diagnose the problem and have me back on the road in 90 minutes.

Austin Rizzotti was very professional and made the purchase of our new auto a real pleasure. He never pressured us to make a sale. The experience was different from any other car buying we have had.

Looked around for a Hummer EV starting in January. When I called Rockville Centre GMC Melissa was a pleasure to deal with. Easy process from beginning to end. 5 star dealership.

I recently purchased a used vehicle from Petar Ardeljan and it was a pleasure. This dealership operates differently from most as they encompass a no pressure environment and are transparent throughout the process. I would definitely recommend.

Great people and great service, would purchase from again. Will also tell others to do business here. They are very friendly and helpful. Only thing that sucks is they are far from me!

Spent almost two hours in the showroom looking at a Terrain—no rush, no pressure. Came and went, took photos, tried the seats. When I finally asked for help, the manager brought the car up front so I wouldn’t have to walk through the rain—and even offered coffee.

Wasn’t planning to buy, just stopped in to look—then I sat in a Buick Encore GX and was sold. Sharp display, snappy multimedia, and that subtle turbo whistle during acceleration? Love it.

Bought a Buick Envision Avenir here last year—best value for the money. Suspension feels like you’re floating, especially on I-95. They gifted me rear window tint and embroidered mats—not even in the configurator. Just a nice surprise from the manager.

Got the Sierra 1500 AT4 because I wanted something with power—and this thing is a beast. The exhaust note never gets old. What impressed me was the five-day trade-in price lock. I needed time to talk with my brother, and they honored it. Even threw in a factory bedliner.

I came in for a door rattle, and the work order actually listed “900g anti-squeak in right weather strip.” Not even part of their standard pricing, but the $14.80 matched what I saw on their site. After the fix, they gave me the old seal in a bag—proof it was done right.
