New and used 2025 GMC Acadia SUVs for sale near Muttontown, 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 saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

The experience and professionalism we received from Mark and the team at the Bomnin was amazing.

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

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.

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.

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.
