Used GMC Sierra 1500 trucks for sale near Port Jefferson Station, NY under $899,990

Best dealership! Incredible customer service! It’s a family working together that’s how I felt. Brian the manager and Joe Handerhan sales consultant and Jorge were a pleasure to deal with!I My husband John&I are very grateful to have been treated the way we were 👍

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.

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.

Bob in service was excellent. Professional, prompt and polite. Made sure work on the car was exactly what was needed.

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?

if you go to this place ask for Oz... an absolute gentleman, and great salesrep ... very rare you find a man like that in the industry... overall 10/10 experience... never even asked me to write a review but my experience was too smooth not too

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...

Great staff, good prices, Greg (salesmen) was amazing, and Jim got me best rate possible even though he didnt have to he kept trying and got me a nice low rate. Now I hope and pray my 2014 Nissan Murano can last me as long as my Toyota highlander did (14 years) before it was totaled while parked. Will look to do business in future with Daddaro Dealer

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!

everything was great. Sales dept. was super. All questions were answered. we were given honest advice. delivery of SUV was handled in a truly professional manner.

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!

I had a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

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.

service mgr is great!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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.

Wonderful service. Thank you Oliver for all your assistance. Definitely will recommend. Love my new car.

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.

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

Great experience had a little trouble with my convertible Zl1’ .Anthony the manager had me come in the following day at 9am .the car was fixed by 920 . Great experience from beginning to the end keep up the the work

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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

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

My husband and I stopped there to look at their Edge inventory. No intention of purchasing that day but getting an idea of what to look for and what we want. The sales person was very laid back and did not put any pressure on us to purchase. When we are ready to purchase I would definitely go back!

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.

I sold a pickup truck to AR Motorsport through Anthony. He was exceptionally nice and easy to deal with. He did not put pressure on me and made me feel very comfortable. Anthony treated me very well and offered a fair price. He was also kind enough to offer me an Uber ride home. Thank you Anthony!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Sean my service provider was excellent and insured my interaction with the service department went smoothly.

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.

I was concerned about going to an out of state dealership, but I was impressed with your high customer service ratings from customers. I felt they were very professional and while pushing us to make a decision, they weren't obnoxious about it. In the end I thought they gave us a fair deal and we love the SUV. I would have no problem making the trip to Massapequa to buy another car.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

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.

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 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.

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck
