Used GMC cars for sale near Selden, NY

"Stamford Dealership is very professional from start to finish. When I first visited their website, I noticed their high star rating, and now I can confidently say they truly live up to it! From the moment I call in, Sergio was welcoming, knowledgeable, and attentive to my needs. Sergio in sales made the car-buying process smooth and stress-free, answering all my questions with patience and expertise. Parker in service was equally fantastic, ensuring everything was in top shape and addressing any concerns with great attention to detail. The selection of vehicles was impressive, and the overall quality of service exceeded my expectations. I highly recommend Stamford Dealership to anyone looking for a smooth and hassle-free car-buying experience!"

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

DeJon Was an awesome salesman I highly recommend blasius as it is always a pleasant experience I have purchased my last 3 vehicles with them and have family that has bought vehicles from them. I love how friendly and personable DeJon was and made the experience very smooth. The finance manager Veronica is awesome. Thank you for my Tesla model Y

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!

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 purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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!

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

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

See Will for the best sales service. He gets to the point and he’s super friendly!

I recently had my car serviced at Napoli Kia in Milford. Courtney my service advisor really made the experience seamless and helped me navigate replacing a tire. Everytime I need service it's has been a pleasant experience.

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Excellent experience buying a 2020 Ford Expedition Limited MAX SUV because my salesperson, Carmine Randello was honest and helpful rather than pushy. Carmine had a way of making me want the car without trying to make me want it.

This truck is great if your not trying to haul 10k lbs. For every day use it's great on gas and I fit everything I need in the bed.

Excellent! Everybody here was honest helpful and transparent. I definitely recommend buying a used vehicle from them.

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.

Very Quick and smooth process. Sale agent victor was really nice. Would definitely do business with them again! Thank you again!

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Baron Honda is the best! 5☆+ in Sales, Service and Parts. All are fantastic, trustworthy professionals, and have been consistently so for all >20 years that I've known 'em.

I always receive prompt and courteous service every time I visit Arnold Chevrolet. I have serviced my car here since I purchased it from this dealer several years ago.

Dealing with Luke and Ryan was a pleasure.. No pressure and very professional. I would buy from this dealership again.

A very relaxed atmosphere no precious sales only the best service good bunch of people

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.

I recently had a wonderful experience at Mazda 112. My sales person Bonnie was amazing. Bonnie was extremely knowledgeable, friendly, professional and helpful. She answered all my questions, listened to what I needed and wanted, and put me in the perfect vehicle!

25 000 miles on it so far No issues at all Power is fine Bluetooth is terrible Memory seats need work Lumbar is a bad design

October 26, 2025, my car needed scheduled maintenance, which included oil change, new filter, tire rotation, and multipoint inspection. As always, Arnold Chevrolet Buick dealership service department was excellent. It was easy to schedule an appointment time that was convenient for me. The advisor, Brandon Coraci, was friendly, welcoming, knowledgeable, and efficient. My wait time in the clean and comfortable waiting room was short. All the service was performed expertly. I have purchased/leased 6 vehicles from Arnold Chevrolet Buick dealership. I have only had the Arnold Chevrolet Buick dealership service department do service on my cars. For 25 years, I have been, and I continue to be, very happy with the sales and service departments at Arnold Chevrolet Buick dealership of West Babylon. I highly recommend this dealership.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.
