New and used 2025 GMC Terrain SUVs for sale near Baldwin Harbor, NY

Came in just to browse. Then I sat in a Buick, took it for a spin, and boom — bought it. The vibe was relaxed, the staff wasn’t pushy, and the whole process was easy. No regrets at all.

Stopped in with a friend just to "have a look." Next thing I know, she picked a Buick Encore GX with a red interior I wouldn’t even choose in Sims. The dealership space is super cozy and photogenic. I was lying on a couch while she debated carpet colors.

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.

Was really anxious about the whole process, especially the paperwork. But the team walked me through it step by step and even helped with my insurance right there. Huge weight off my shoulders.

They actually listen. No sales lines like “these won’t last” or “someone else is already interested.” Just respectful, pressure-free help. It made the process easy and comfortable.

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 came in with just a few questions, and they welcomed me like a regular. The manager walked me through the Terrain’s features while I sipped on coffee—no pressure, no sales pitch. Honestly felt more like chatting with friends than being at a dealership.

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.
