Used GMC cars for sale near Mastic, NY under $899,990

We’re extremely pleased with Eagle Chevrolet, and specifically the service manager Stephen. We were out of town and in Long Island when our 2023 Traverse developed an exhaust issue with the engine. Stephen and the service team did a great job getting us back on the road. We would highly recommend Eagle Chevrolet and the service team for their Great service.

Friendly staff, great price for the car. There was a far bit of waiting around but with the volume of cars they are shifting on a daily basis, it was kind of expected. From the very short test drive to driving out with my car was around 45 minutes.Would definitely use then again.

Dominick was very patient with me and had a wonderful experience buying my third Lincoln from Bright Bay. Everyone at the dealership from the salesman to the worker who greets you at the service are gracious and professional.

Perfect transaction no issues, this dealership is my family’s first choice now. Fast service friendly staff and very nice show room, thank you port Jeff dodge!

This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

I visited on the second day being opened and had a great experience in buying a 2022 Explorer and trading in a 2016. It was seamless. Had an issue with the new car that turned out to be a factory defect that they had Ford correct. All good. I’ll be back.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Had a great experience with Oz. He took his time and explained everything. Zero pressure! The buying process for VW TAOS was easy. Would like to thank Jared in finance as well for explaining all the details. Definitely recommend

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Very very happy with the whole experience. Everyone was very professional, quick courteous. Everything was taken care of in a timely fashion probably one of my best experiences ever at a car dealership recommend it highly.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Eder and Ralphy great dudes great experience with them treated absolutely awesome form the moment I walked in…. Definitely will be sending friends and family their way… again awesome experience

This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

Persons at Eagle Riverhead Chevrolet, were friendly, professional and respectful. Make us feeling among friends

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Great customer service. Great manager and staff at Hertz Rental in Smithtown, NY. They were polite, quick and easy. I will definitely recommend the place to friends!

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Very kind, professional and most important FAIR! I was extremely stressed over my car situation and it was a weight lifted off my shoulders! Down to earth and extremely understanding! I am very satisfied and will reccomend them to those in need of a vehicle

I bought a 2016 Yukon XL and after just a few weeks, a vehicle ran a stop sign and totaled the vehicle. However, the vehicle was so sturdy that even though it was a huge crash, I was not injured more than bruises. I replaced it with a 2018 Yukon XL because I know it is reliable and safe.

Excellent service and really great selection. I was able to leave with a car the same day. I would highly recommend seeing Capital Motor Group, first

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Great customer service Paul and Rich get you the car you want guaranteed and good condition

Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

Bought my car at Best Buy Auto stop . The service was excellent. Dan the manager was exceptionally helpful and had good overall experience. Recommend this place to shop for used cars before buying elsewher

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

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 fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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 styling and interior. nice features and acceptable performance. overall my Denali is a superior product to similar vehicles. I would recommend this GMC Acadia.

Eder and ralphy great people helped m with the purchase of the 2022 Honda hrv thank you guys !!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Excellent Service, Asking Price Was The Price I Paid No Hidden Nonsense Like The Rest.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

I want this truck if I can't get help with finances I'll try againfri and ill have cash. I want it 100percent I've only dreamed of owning a truck like this and now if the Good Lord willing and the creek don't rise.a dream might come true.,!!!!!! I love everything about this ride.just rite for the open road.

Transaction was very smooth from start to finish. Sales staff was very professional, especially Greg and Joseph who were very responsive.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.
