New and used 2026 GMC Terrain for sale near Merrick, NY

Small detail that impressed me: when I picked up the car, they gave me floor mats as a gift. Maybe minor, but it showed real attention to detail.

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

I was pleasantly surprised the manager didn’t try to upsell an expensive trim. Instead he said, “You don’t need that, don’t overpay.” Felt refreshing.

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

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.

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.

Only thing I have to say is I wish I had purchased my Sierra truck from this dealership. I drove pass my purchase dealership just to do business with Rockville Center GMC Andy Melo and crew did a splendid job on getting me in and out and safely on my way.

I live nearby and often passed by. One day I stopped in out of curiosity. Two hours later, I walked out with a Buick Encore GX contract. Funny how that happens when mood, people, and timing align.

I’ve been driving my car for two years—no squeaks, no breakdowns. And when I need service, it’s nearby and welcoming. Never feel like I’m wasting my time.

Car was serviced for an oil and filter change and a tire rotation. I was in and out in one hour. Very please with the overall service and fast turnaround.

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