New and used 2025 GMC Sierra 1500 trucks for sale near Manhasset Hills, NY

Very good service I was taken on time & kept informed on the progress of the repairs. It was quick & easy. I will not hesitate to use them again

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.

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.

Fast and prompt service. Kept me informed of repair progress and very professional and friendly. Would recommend to all. Services completed as promised in one day.

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.

Excellent service. Ask for Delano Ashmeade. Smoothest and easiest transaction you'll ever experience. A1

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.

Very helpful service from Petar and extreme transparency very truthful and genuine 👏 looking forward to purchasing from this dealership

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.

I highly recommend Rockville Centre GMC Service. I own my 2017 Acadia and over the last several months I needed repairs or replacements made to several high ticketed parts. I felt comfortable dealing with Stanley the Service Advisor and Keith the Service Manager. They were both polite and professional. They took the time to explain each necessary job to me and I was satisfied with the work performed.

This was a very good experience. North Bay has a straightforward and honest approach to their dealings with clear pricing and costs, good communication, and a friendly/helpful staff.

Nice facility, clean and comfortable waiting area. Professional customer service from the staff. I would visit this dealership again in the future if necessary, hopefully I won't need though...lol

The salesman was very knowledgeable, the finance department was excellent. From start to finish, it was a pleasant experience. I highly recommend buying your next vehicle here.

The dealer was great. But the apple play in my 2024 Sierra is not yet supported. What the xxxx is that about? How the heck can you sell an incomplete vehicle? I?d like to know when it will be fixed. And it better be soon.

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.

Sean my service provider was excellent and insured my interaction with the service department went smoothly.
