New and used 2026 GMC Terrain for sale near Islandia, 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 have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

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’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

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.

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

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

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.

GMC in Rockville Center is one of the best car dealerships and car repair service places that I have been to in years. The people that work there are top-notch and the work they do is even better. Thanks, GMC Rockville center!

Great service Stanley did a great job in keeping us informed of the process and offered packages based on miles on car. Thank you. Great job

Jesus has been my go to guy for 15 years. Have bought 5 cars from this dealer very professional and knowledgeable. Dealer is in my town and close incase of services needed

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

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 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.

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.

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.

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.
