Used GMC Sierra 1500 trucks for sale near Hempstead, NY

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.

We had a great time with Matt Kass, he didnt seem pushy he took his time let us make a couple choices on the car then gave us the right car at the right price Im so glad we had the right salesman to work with Will send all my family and to him

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!

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

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 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.

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!

Service has been good too. I work nearby and bring my car here for maintenance. I call to schedule, and when you arrive they already know what needs to be done.

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

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.

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

Rob and Danny helped me purchase my Ford F-250 We love our experience they were very helpful!!

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.

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.

Made a long distance purchase. Was very leary buying a car that I was unable to test drive. But Jordan pretty accurately described the car and even offered to help set up an independent person to evaluate it. Came across as a reputable business that I would work with again.

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.

Customer service is above expectations. Not a long wait to checked in. I?m big on customer service and they are the best. I was apply to get a Saturday appointment because of work the same week I called.

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 recently purchased a lexus gs350 and I must say I had a great experience the service was courteous professional and they help me out with no discrepancies the car runs great and runs in excellent condition, I would definitely recommend to someone looking to buy a new or used car.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

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

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Dear East Hills of Roslyn , We my wife and I are so happy to haves met such a great gentleman such as Ricardo Nelson , to go out of his way and making us feel at home in your dealership .Mr. Ricardo Nelson we both tip our hats to you . God Bess . Your friends for ever , Jose and Monica .

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.

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!

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

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.

Island Auto Group is the place for 🚗 Let me share my first car buying experience in New York. As someone with zero prior knowledge of how dealerships work, it was incredibly challenging and stressful at first. For over a month, I hunted for a reliable, low-mileage car with excellent safety features, low maintenance, and something within my budget. I ultimately decided between a Subaru Crosstrek or Mazda CX-5. I checked online sites like Cars.com, Carfax, and CarGurus, visited around 10 dealerships (both independent lots and franchises), made tons of phone calls, and even explored Carvana and CarMax. Too many places baited me with low online prices, only to pile on thousands in hidden fees once I showed up—things like mandatory down payments, wear-and-tear charges, inspection fees, and dealership add-ons. But from this experience, I learned a lot about how dealerships really work and gained some valuable knowledge: never fully trust the prices posted online without confirming the true out-the-door cost in person. After five frustrating in-person visits, I was ready to give up on traditional dealerships and just overpay at CarMax to avoid the headaches. That’s when I spotted a listing on Cars.com from Island Subaru. The vehicle photos clearly stated “No hidden fees, no extra fees – fully transparent OTD price.” Skeptical after so many bad experiences, I decided to try one last time and walked in without an appointment or even a phone call. Right away, I met sales representative Christopher Chavous (everyone calls him Chris). He was patient, professional, and didn’t bombard me with unnecessary questions or personal info. He showed me the Crosstrek I was interested in, sat with me for two detailed test drives, and explained all the features thoroughly. The standout moment? Chris gave me the true out-the-door price immediately—no games, no surprises, exactly matching the online listing with zero hidden fees. In an industry full of tricks, this level of honesty instantly built trust, which is everything when buying a car. After some fair negotiation, the manager approved a solid discount, and we sealed the deal that same day. Since it was Saturday and close to closing (they couldn’t finish the NY inspection), they went the extra mile and loaned me a brand-new Subaru Crosstrek to drive until Monday when my car was ready. Finance manager Yuri Miyakawa handled the paperwork smoothly, got me a great rate, and made everything straightforward. But Chris truly went above and beyond—he guided me through the entire purchase process and even helped set up my first car insurance. The initial quotes were sky-high for a new driver, but Chris personally called the insurance company, advocated on my behalf, and somehow got my rate reduced to half the original quote! That kind of dedication is rare. The whole team—the manager, Yuri, Chris, and the rest of the staff—was genuinely helpful and made me feel valued. I drove home in my Certified Pre-Owned Subaru Crosstrek Limited with just 9k miles, at the exact negotiated price, with all documents perfect, a full tank of gas, a fresh car wash, and three free oil changes for the first year. Island Subaru transformed a potentially nightmare first-time buying experience into something positive and memorable. Their transparency, honesty, and outstanding customer service set them apart. I’ll definitely recommend them to friends and family, and I’ll be back for my next car. Thank you, Island Subaru team—especially Chris for your incredible support throughout! 🚗💯

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

I have been going to this dealership since 2009 even after a few name changes the service remains the same. I would definitely recommend this dealership.

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...

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.

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.

I used the service department on my Lexus rx 350 and Diego was great. Very accommodating. They replaced my wipers and now they work great. Diego was really on top of things. He arranged for me to even get a loaner car while they were servicing my car.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.
