Used GMC cars for sale near North Massapequa, NY

Received first rate service from my advisor, Lauren! Was able to make the appointment through the website without any issues, which made the experience even better.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

You have the NICEST people working there! Cordial, professional, and extremely helpful. 10 STAR STAFF!! Now let's talk about your coffee...lol...sorry can only give the 2 stars!!!! lol

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

"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.

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!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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

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.

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

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

The service was done well. Dominic was a professional and did a great job putting everything together.

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!

Mi experiencia en 5 Star fue mejor de lo que esperaba. Muy atentos, explicaron todo en detalle y me sentí muy cómoda durante todo el proceso

I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

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

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.

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

Best experience ever love it at GMC best customer service free WiFi free tea very experienced staff and very knowledgeable staff I love it there

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!

Kevin has been an incredible sales person. One of the best I’ve ever had will continue to business with them.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I purchased a used car from Greenwich BMW and couldn’t be more pleased with the process. As an out of state buyer, I was concerned with the potential tax and DMV issues. My sales person was very professional and answered all my questions and explained the process thoroughly. Upon arrival, the car was in impeccable condition, as stated in the advertisement and they honored the trade in value discussed over the phone. The loan process was quick and there were no surprises! All in all the best car dealership I’ve had.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Fast great service . Courteous staff. Easy to make appointment. Kept me updated the entire time vehicle was in shop. Highly recommend. Definitely recommend to family and friends

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

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

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

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.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

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

Awesome car! Reliable and I have 200,000 miles on mine and never had a major repair. Comfortable. Good for towing. Easy to hold a lot of people. Speaker quality is good. I’ve owned about 6 different cars and this is my favorite by far.

First off I would recommend this dealership to all my friends.. I went in to purchase a 2016 maxima from the minute I got in… Rehan was on it he made me felt at home not pushy was great with me my credit wasn’t so great and he help me get the car with no haggle… thanks Rehan we will see u soon for our next one.

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!

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 selection found my 2019 Honda Odyssey there the sales rep was great the manager was cool and the finance lady was excellent I had a overall good time with my purchase I recommend all who are looking for a new car check them out you might find the right car for you

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.
