New and used 2026 GMC Acadia for sale near West Islip, NY

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.

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

The staff was so professional with smiles on their face. I am big on customer service, and this staff defines the word. I will recommend this dealership to everyone that drives a Buick

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

Very good I had a wonderful experience there. They did great work on my car. I will bring back more of my cars to get service there.also

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.

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

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 bought a 2022 Escalade ESV in 10/2023. From start to finish there was no hassle I saw the vehicle and did not purchase for over 2 months shopping around for a better deal. I went to many Cadillac Dealers across Long Island and they did not take me seriously. When I told them what I wanted my payments to be they didn't even attempt to really search for a vehicle that could match my interests. This Dealership allowed me to test drive without prejudice and also were totally patient until I was finally able to clear title problems with my Credit Unions because of NY State Laws and then Finance with Cadillac. I was shown the vehicle features several times to at least get the vehicle off the lot. My payment was 1265.00.. but now I'm down to 1065.00 per month. I would recommend this Delearship to anyone in the world. They go above and beyond in Customer Service.

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.

Stanley is amazing always keeping me updated and make sure my truck is always returned in better condition than it was. They are a great dealer

Staff was very helpful and informative , I was able to locate the car I wanted, tell the sales person , and he was able to get me approved and drive out the same day

Stanley in the service department was great, as is everyone at RVC GMC! Had the oil changed while I waited, and it was done promptly as promised.

Friendly courteous dealership with interest in your personal satisfaction. Fair pricing and finance terms to suit your budget. Overall good purchase experience.

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.
