New and used 2026 GMC Sierra 1500 Elevation trucks for sale near Oyster Bay Cove, NY

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.

Asked if a full remote purchase is possible - they said yes: you apply online, handle financing, then just come in to sign. That’s convenient if you don’t live nearby.

Just bought a new 2025 Acadia, great deal and great dealership, Arnold was the best associate to work with, very professional and easy to work with, whole transaction was a pleasure, I definitely recommend this establishment and Arnold , I give the place 9 thumbs up out of ten, you won’t be disappointed!

Worked with me the whole way to get my car serviced when my car engine seized stemming from a recall. They provided me a loaner until the part was sent from the GMC main warehouse.

My vehicles have been serviced here since 2009 and as always quality work was performed in a timely manner. My service manager was Andy who was professional and very polite

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.

Always take care of theirs customers honest and professional been going there for the last 16 years. Brought a new car last year a 2024 GMC Acadia. Highly recommend them. Travel from Brooklyn for all my services.

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

My vehicle was being serviced at service center.Staff was very polite.

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

I bought my 2025 Sierra EV out of state but am here in Long Island for a few months working and Rockville Center GMC was the only GMC dealership near by who would honor my GMC warranty. They have been great!!

John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

Recently I wrote a complaint review regarding an issue I was having with Milea regarding collision body works repairs. The repair issues have been resolved. Milea Service Manager Angelo contacted me, service was performed on my vehicle, dents were repaired. Problem was corrected satisfactory. Milea made good.

I recently purchased a new GMC. The customer service provided at Bomnin, Nanuet was exemplary. My sales associate, Arnold Polanco was both personable and professional. Negotiations were respectful and he took the time to listen attentively and made certain that all my questions were answered. I never felt pressured to make a decision. Of significance, my spouse had purchased a vehicle the week before and his positive experience made it possible for me to want to return to the dealership to purchase a new car. Arnold made sure my car was cleaned and ready at pick up and he even took his time to walk me through every feature included in my purchase. I was impressed with my overall experience at Bomnin, Nanuet.

They provide a professional and courteous service.
