New and used 2025 GMC Sierra 1500 trucks for sale near Glen Head, NY

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 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.

Marilyn Bergin was a pleasure to deal with. We had a few changes during our process and nothing was a problem. Had a great experience and would definitely refer Marilyn to anyone looking to buy a Chevy.

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.

Rich Santana was a pleasure to deal with, we will be back in the future.

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.

If I had to sum it up—it’s calm, respectful, no pressure. They listen, ask smart questions, and never push “what’s your number?”

It is no stress when I bring my car to RVC GMC. Each person I have dealt with has been helpful, friendly, knowledgeable, and professional. RVC GMC is reliable, efficient, and timely. The waiting room is clean and comfortable. There is a large TV and you can help yourself to a hot drink. I?ve also gotten a courtesy ride home from them.

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.

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

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.

Great dealership to work with. I had the pleasure of dealing with Zeeshan, Willie and Akbar and I have to say it was the best interaction I had in any car sales. They were professional, courteous and actually cared about what we wanted. Most importantly, they were honest. Communication was too notch and I was updated every step of the way by text or call. They went out of their way to make sure we had the best sales experience from beginning to end. The car itself is beautiful and they didn't cut any corners in the sale. I wouldn't hesitate to recommend them to any one and when I'm in the market again will definitely be a return customer.

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

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.

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

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.

Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

Buying my Buick was a great experience, they give you time to breath while looking around then approach for help and answer questions! Service area is alway great, always work with you to get the appointment you need! Will be leasing my next car from them for sure!!
