Used GMC trucks for sale near Hempstead, NY

Great Experience!!! Smooth process, Lorena was awesome, excellent value, stress free pickup, highly recommend to go see Lorena.

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.

Tim, the Service Department Manager, provided excellent services (from initial phone quote to drop off to cost adjustments and final pick up experiences).

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'd been treated in a great manner at Stamford Ford, I would have to mention Marco and Juan Zuleta they're so experienced and as persons so gentle, thank you guys!!

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.

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!

Ronny Terraferma was amazing. Treated myself and my daughter like family. He was honest and professional throughout the entire process I will definitely will return for my next car!

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!

went there for the first time about 1.5 weeks ago for service - great experience - Emily was amazing...personal yet professional - she stayed in contact with me and kept me updated about the car, every step of the way - highly recommend their services -

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.

It has been a pleasure working alongside Carlos at stream auto. He and his team made it an easy smooth transition for me to leave there with a great car and a smile on my face thanks again team five stars to Carlos

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.

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.

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.

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

Very kind helpful and make sure you come out with a car. The most I like about dealership is there workers

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

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...

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

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Tom Cali is an excellent salesman. He is so professional, patient and helpful. We went to buy a pre-owned Lincoln Nautilus or Aviator and he was so patient with us and just made the whole experience a Real Pleasure. We will be recommending everyone we know to go to Bright Bay Lincoln and that is where all of our future purchase will be. Also, Prescott in finance was honest, caring and wonderful too. FANTASTIC EXPERIENCE ! ! !

The absolute best dealer I’ve been to by far in my search ! Low prices clean cars and low interest rate!!! Will refer my cousin to you as he’s looking to buy next week! Thanks Euro A++

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I purchased a 2026 Equinox from Mr Tom LoBue, who was professional & courteous through the process & made sure I got the vehicle that I wanted. Thank you.

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

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 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

Shopping for a used car?? Stop at GRAND USED CARS in Little Ferry NEW jersey and speak to Anthony!!! HE is a friendly car salesman who will go out of his way to get you in the car you want!! ANY problems after you get the car he will go out of his way to fix the problem and help you out. I bought a 2005 Jeep GRAND Cherokee Laredo and I love it!! I will go back in a second to by another car!

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

I recently purchased a 2023 BMW X5 from Island Auto Group, and the experience was outstanding from start to finish. I’ve bought and leased several vehicles over the years, and this was easily one of the smoothest, most transparent car-buying processes I’ve had. From the moment I arrived, the team was professional, knowledgeable, and respectful of my time. There was no pressure, no games, and no hidden fees, which is something I really appreciated. They walked me through the details of the BMW X5, answered all my questions clearly, and made sure I understood every option before moving forward. The pricing was fair and competitive, and they were upfront about everything — trade-in value, financing, and next steps. The vehicle itself was in excellent condition, exactly as advertised, and the delivery process was seamless. What really stood out was the customer-first approach. It felt like they genuinely wanted to earn my business, not just close a deal. The entire process was efficient, professional, and stress-free. If you’re looking to buy a pre-owned luxury vehicle like a BMW X5, or honestly any car, I highly recommend Island Auto Group. They made what can be a complicated process feel easy and straightforward. I would absolutely buy from them again.

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.
