Used GMC trucks for sale near Massapequa, NY

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!

A + all around went above and beyond to help me out very kind and helpful was in a serious pickle and everyone helped me out immensely

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.

Excellent Service, Asking Price Was The Price I Paid No Hidden Nonsense Like The Rest.

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.

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.

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

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

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 .

Laurie Dunn was a pleasure working with while the dealership was fixing my SUV, she kept me UpToDate with what was going on. All in all, everyone I spoke to while at the dealership was very helpful from the showroom members to service even the valet guy.

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

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

My experience with Mike was great very informative. Took his time to explain everything about the vehicle. Everything about the loan. Try to get me the best loan deal which he did. I have no complaints. Wouldn’t hesitate to purchase another vehicle from this location.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

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.

Gina did a great job. The process was very fair and straightforward. I would definitely purchase a vehicle here again.

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!

I worked with Daniel Brendler. Because of his knowledge, experience, and easy going personality, I will definitely come back to him when I am ready to purchase a vehicle.

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.

Every thing was smooth except for a couple of minor Issues that can be resolved, Thanks Guys

I bought this truck new 1/22. Have put over 100K miles in 2-½ years. No problems. Have 5.3L and 10-speed. Very reliable. Nothing has gone wrong. I feel the seat cushions are too short for someone over 6’.

I just wanna start by saying most of the bad reviews are from people that bought cars with recalls. But is not a reflection of the dealership. My experience with them was phenomenal. They went above and beyond and treated very well. I flew from maine to ny. When I arrived they noticed I was very tired and offered me an orange and coffee and also gave me the option to rest in one of there vehicles till all paperwork and the car was detailed. Shout out to Pablo and the manager for a great experience. Highly recommend!!!

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.

Thanks for the great work and fast turnaround. My advisor Andy was very communicative and transparent. I appreciate the loaner car which was very helpful to my family. I was impressed with all the work that was done to my car. My car feels like new again. I would definitely be back to this service GMC of Rockville Centre. Highly recommended!!

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.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

Great experience. Ask for Pablo. Very personable. Received a great deal!. Thank you again Pablo

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

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.

Had my 2024 Canyon for exactly one year. Not a single real issue once over the air update was done and that only affected the radio. It was an AT4 in desert sand metallic. I traded it for a 2025 Acadia, as I missed life in an SUV. However if you want a truck, I’d highly recommend it and specifically the AT4 model. It’s got meaty tires for pothole protection, it’s able to tow more than you can imagine, it looks super amazing and you’ll have lots of thumbs up and positive comments when you get gas, etc. updated tech was more than you could ask for. 4WD auto mode worked flawlessly. Engine had a nice little growl that I miss too. Let me say if you are a truck person or want to be a truck person, it’s a perfect mid size truck. Mine was 100% and am missing it yes but love the Acadia because it’s also a great vehicle. Got the AT4 Acadia and for my situation it’s perfect.

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 !!

Great Trucks! Owned quite a few and they never let me down and seem to hold their value. I will keep buying them for as long as I can.

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.
