Used GMC cars for sale near Mastic Beach, NY under $25,000

I bought a Cadillac CTS2013 the staff was great and my car is beautiful I love it .I would recommend this dealership to my friends

This truck is exactly what I was looking for! Very well kept and in great condition. Great ride and interior is like new for this 2013 Yukon. All the comfort and space I was looking for to get ready for the winter!

Very friendly, enjoyed the conversation! We are our of towners, gave us advice on what to do and visit while in town.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Great honest place! I found my car online went in and the price was the same! There were no fake fees and I all in all it was a great experience

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.

Abraham in service handled my recall service for my 2013 Accord and it was seamless. They gave me an appointment for the same week I called and the car runs better than ever now!

Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .

I like how honest and upfront this dealership is. I literally spoke with them on Thursday and picked my car up on Saturday morning. They took care of everything for me so this way on Saturday I spent about an hour there signing paperwork and was out in no time. Lexi is a sweetheart! I would do business here again if I ever need a car in the future. Don’t go to a different place and get scammed. Come to Riverhead Nissan and be treated the way you deserve and don’t get taken advantage of!

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

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

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.

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.

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.

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

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!!

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.

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

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.

Best used car purchase experience I have ever dealt with. They were patient, helpful and did everything to make sure I was comfortable with my purchase! Highly recommend Dan and team

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.

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

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.

Kevin was wonderfully helpful without being pushy. It was a positive experience. He offered everything over and above.

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Fantastic service very professional timely on paperwork car was ready for test drive would purchase a vehicle from them again

To be honest, this SUV impressed me with the great performance even with the small 1.5 liter engine, and huge space inside, it rides like a bigger vehicle, very responsive on the highway and very quiet cabin. My wife really liked it.

Had a positive experience with this dealership. My interaction was with the sales representative Tom W. He and the financing representative Marty were pleasure to work with and efficient. Tom and the team were patient answering my questions and addressing my needs. Resulted in my purchase of a certified pre-owned vehicle. I would recommend this dealership.

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

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.

It’s beautiful,gas efficient,and has plenty of leg room inside !! I love everything about it !I brought it all the way from Baytown Texas to Atl

My experience at Lemans was nothing but amazing. Never felt pressured to purchase a vehicle, they made me feel comfortable and they’re well respectable. Diego was excellent especially. Highly recommended dealership to go to

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Rodrigo is great sales person i buy 3 cars from them good dealer no hiding fees

I really like my nw, to me, 2015 GMC Sierra Denali. The salesman, Terrance Lin was very efficient, helpful and courteous. Thank you very much.

Great to deal with from start to finish. Listened to our concerns and repaired any and all items. Quick and professional.

Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.
