Used GMC trucks for sale near Jericho, NY

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. :)

"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

Excellent service! Izzy and Hamad, are very professional, very knowledgeable and very friendly! I would recommend that facility to everyone!! Thank you and Happy Holidays!

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!

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

Received a call 5 minutes after entering the Car I was interested in. Salesperson very friendly and knowledgeable. Still thinking about the car. They are at the top of my list.

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!

Honest dealership and car tech 's. The only problem is that this is a small dealership and they need more help in getting the back log of cars needing repairs moving faster. They should also have Saturday appointments in which they do not to do oil changed and minor repairs. Most dealerships have Saturday appointments but this dealership don't

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.

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

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

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

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.

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

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.

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

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.

Coach is a true gentleman and makes you feel like you know him forever. he goes above and beyond to help you get your vehicle he treat you like family. I can’t thank him enough for helping us get a vehicle if you ever looking for a vehicle, please ask for Coach. Everyone that works. There is very friendly and helpful. thank you again Coach for everything. My experience was amazing

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

I had an amazing experience over at Metro Honda. Jesse was very knowledgeable and professional. He made sure I understood every detail for my new Honda Accord. Thank you Jesse for all your help

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

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.

This Jeep service location always goes above and beyond. Manny takes such good care of me and makes sure everything goes smoothly. I honestly can’t say anything bad about them.

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.

Took about 3 hours but it was worth it. They were able to purchase and pick up the bulbs to install in the vehicle properly.

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!

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.

Excellent dealership I was in and out quick with my daughters new c300. They got me approved even with my itin at a very low rate. Clean cars inside for sure go check them out !!

First , I bought gas 6.0 , the diesels are great if you have serious towing needs. You just need to realize no matter how well you maintain a diesel it will at some point have an expensive repair. I've had my truck about 12 years. Regular maintenance , a few batteries , couple sets of tires and a MAF sensor. I tow a couple different trailers and the heaviest is less than 10k loaded. Towing , zero issues , no band aids , no overloads , no equalizing hitch , no sway control. Simply not needed. Drives amazing, stops great, Roughly 10 to 12 MPG towing. Unloaded driving at 60 / 65 on cruise solid 15 to 16 MPG. Yes , it won't pul the hills like a diesel but thats a small price to pay for an absolutely amazing truck. I want a new truck in the worst way but just can't part with this truck. A very good truck if you find a clean well maintained one.

Amazing service!! I drove from Middlesex county NJ and I enjoyed the ride, Tyler Monninger did a great Job! Thank you!! recommended this dealership to anyone

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.
