We traded in our 2019 Buick Encore for this Terrain. Let's just say WOW on the room and comfort. We travel back and forth from NC to Ohio as family lives in both States. Well the Encore was nice on gas but not comfortable on long trips at all. This has great leg room (heated seats (both back and bottom) and this is a game changer for me with my arthritis. The cameras in this car are awesome. You can see clearly what is behind you when backing up. The lane assist will give you a little buzz in the seat on the side you have drifted too or if you are getting too close to an object or person when backing up. Nice cargo area. The back seat can also handle 3 adults with enough leg room. It's very comfy back there, I road in the back on the test drive since I sometimes sit in the back on trips so I can n change positions more. The 15 inch info center is impressive for sure. Still learning how to use it. If you want comfort in a nice looking SUV this is the one for you.

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 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.

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

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

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.

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.

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.

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

John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

Buying my Buick was a great experience, they give you time to breath while looking around then approach for help and answer questions! Service area is alway great, always work with you to get the appointment you need! Will be leasing my next car from them for sure!!

Great experience all around, gave me a a fair trade in valve, would highly recommend.

Recently bought a used Lincoln from Blasius. Great experience! Ken McKay is a great guy. Took car of everything. Great car, great price, great experience. Wouldn't hesitate to go back. And thanks to Chris in finance as well. Another great job.

The salesman was great. No pressure and willing to negotiate. The finance guy was even better. Overall great experience buying a car.

Just bought a Colorado from Blasius Branford and impressed by the quality of vehicle, price and service. Joey Posa and Mike De’Angelo were great to work with—highly recommend

Mike and Chris were awesome. Chris in finance was extremely helpful. Would definitely recommend. Great service department also.
