Used GMC trucks for sale near Central Islip, NY

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 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!

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.

Steven was very helpful! He took the time to explain everything and worked with us on getting exactly what we wanted!

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

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

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 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.

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

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

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

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.

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'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.

They did the most possible deal and more for me. Kevin and manager are so nice and want the best for me. I love the delealership.

I love my 2022 GMC Canyon Elevation. The V6 engine is great. Good gas mileage, even for the way I drive it! Great comfort and very stylish. All around, just a great truck.

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.

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

I purchased my new GMC Canyon Elevation 4x4 Crew Cab a month ago and it's been a pleasure to drive to this point. I think it rides very well for a truck which disagrees with the Cars.com review. It has plenty of power with the V6 and 8-speed transmission for passing. I have yet to tow with it but that's coming next month when I tow a flat bed trailer with 2 ATV's on it. I love the 18" tires and blacked out wheels which gives it a much higher stance than my old 2010 Colorado 4x4. The truck stands very tall for a mid-size model and it gives me a great view of the road behind the wheel. I love the Infotainment system with Sirus XM, Spotify, etc. The soft-lowering tailgate is nice and so is the auto-locking feature. It doesn't have standard features such as lane departure, blind spot warning, adaptive cruise control, etc. My wife's Subaru Forester came standard with those features whereas the Canyon has them as an add-on option. Not a deal breaker. The lack of decent rubber all-weather floor mats were a disappointment so I had to order them along with splash guards. I'm not sure about the Goodyear Fortitude tires in the winter since the reviews don't rate them well in deep snow. If I have to, I will install 4 snow tires. So far I love the truck and I love the Satin Steel color. It's a major upgrade from my 2010 Colorado 4x4. It's a bit early but I would definitely recommend this truck to a prospective buyer.

Jessica is the nicest and honest sales person I have ever had! Very knowledgeable and helpful. Dave Q the Sales Manager is honest, knowledgeable kind. No pressure and took very good care of my husband and I. 10/10 I recommend!!

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

I bought a car from this dealer (land Rover), everything went well , the staff were friendly and helpful. Special thanks to antoine wilson , he was very professional , helpful and kind. Thank you

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!

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

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.

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

Prompt, Conscientious, Knowledgeable Excellent Service!!! I Strongly Recommend!! All Service Staff were pleasant to deal with and answered all my questions!!

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.

The Salesman Jay was very helpful and outgoing to help us find the right vehicle

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.

Worked with Jon! He answered all my questions and made the whole process very efficient!

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

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

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!
