New and used 2026 GMC Terrain SUVs for sale near Herricks, 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.

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.

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 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 had a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

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 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.

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.

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.

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.

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.

Services were professional friendly and courteous. The service writer was informative and helpful with answering my questions. A clean comfortable environment. I would recommend this dealership to a friend.

A + all around went above and beyond to help me out very kind and helpful was in a serious pickle and everyone helped me out immensely

Thanks for the great work and fast turnaround. My advisor Andy was very communicative and transparent. I appreciate the loaner car which was very helpful to my family. I was impressed with all the work that was done to my car. My car feels like new again. I would definitely be back to this service GMC of Rockville Centre. Highly recommended!!

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

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.

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.
