Used GMC trucks for sale near Islip, NY

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.

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. :)

My review is about Paul Whaley; i have only good things to say about him. Paul is a young man, very respectful, professional, attentive. He is very patience young man and always in contact with me without put pressure on me .Thanks Paul for all your efforts to close this deal, and I hope we do it.

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!

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.

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

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

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

Chris Castillo and Orlando Zayas were extremely professional and helpful. They made the car buying process easy. Chris was extremely patient and knowledgeable. Orlando went out of his way to make it all work. Thank you!

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.

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

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.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

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 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.

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.

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!!

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.

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

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.

Great experience. Very knowledgeable and worked with me to find my perfect car. Will definitely be coming back!

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

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!

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++
