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

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.

if you go to this place ask for Oz... an absolute gentleman, and great salesrep ... very rare you find a man like that in the industry... overall 10/10 experience... never even asked me to write a review but my experience was too smooth not too

I had a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

Great service from Zach. Very knowledgeable and thorough. Will definitely recommend him and Generation Buick GMC to my friends and family.

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!

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.

Wow what a complete difference in professional service from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated.

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.

This is our 7th vehicle between grand prize and Bomnin. Wilbur Pichardo has been our salesman each time and we have been very happy with Will.

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

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.

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

Everyone was nice and communicated well. It was easy to work in the service lounge and I enjoyed the coffee there. I would schedule more service here in the future.
