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

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.

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!!!

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.

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

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.

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

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.

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 made a last minute appointment and was accommodated in a timely fashion. The service was excellent. I wax just in there for an oil change and a tire rotation and it was cheaper at the dealer then on the outside.

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.
