New and used 2025 GMC Terrain for sale near Cold Spring Harbor, NY

I highly recommend the entire team! Petar was very responsive right from the initial call. He put the vehicle on hold for me 2 days ahead knowing that I was driving 5 hours from Maine to drive and potentially buy. When I arrived, it was fully detailed and sitting right up front. There was a mechanical issue that my husband found. Lloyd entered the picture. Lloyd immediately drove it down to the service department, they diagnosed and fixed immediately. It took a couple of hours....but the guys gave us a recommendation for pizza and bought our lunch. Gene jumped in on the tech side and got me all set with the app and answered all of my questions. Ashley in finance was also really helpful and got our paperwork done quickly!! Overall 7 out of 5 rating! Everyone worked well together, treated us VERY well, were honest and most importantly, authentic. Call Petar and team for your next 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.

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.

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.

Sean my service provider was excellent and insured my interaction with the service department went smoothly.

The Rockville Centre GMC team did a tremendous job with my vehicle. They were timely and always was in communication with me about my vehicle

Tony was there!!! He was my go to guy for service on my three GMC trucks. He?s retired but still visits. Good to see him.

Andy is very knowledgeable and professional. He got my car in and out quick. It was fixed in no time. Love this Dealership. Mechanic is great also.

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.

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.

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.

Great dealership to work with. I had the pleasure of dealing with Zeeshan, Willie and Akbar and I have to say it was the best interaction I had in any car sales. They were professional, courteous and actually cared about what we wanted. Most importantly, they were honest. Communication was too notch and I was updated every step of the way by text or call. They went out of their way to make sure we had the best sales experience from beginning to end. The car itself is beautiful and they didn't cut any corners in the sale. I wouldn't hesitate to recommend them to any one and when I'm in the market again will definitely be a return customer.

My first car from them was back in 2019. A Yukon XL. Then came the trade-in. Then another new one. Just picked up my third from them. A Buick Encore. And the best part? They remembered my name. That kind of consistency builds trust. People don’t rotate every six months here. Everything feels steady.

My first purchase here was kind of by accident. It was the closest dealership. But the second time, I came back on purpose. Because once you know they won’t lie or change numbers last minute, you stick with the place that gives you peace of mind. This place does exactly that.
