New and used 2025 GMC Acadia SUVs for sale near Cold Spring Harbor, 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.

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!

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

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 people and great service, would purchase from again. Will also tell others to do business here. They are very friendly and helpful. Only thing that sucks is they are far from me!

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

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

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.

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.

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.

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

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.

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.
