Used GMC Sierra 1500 trucks for sale near Islip Terrace, NY under $899,990

Returned a lease and leased a new Jeep Wrangler with ease. The process was seamless. Would recommend this dealership for all your car needs.

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

Excellent service by Anthony. We have bought many cars from Anthony Pavone. He always does the right thing?

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

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

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!

Excellent dealership gave me great customer service easy and efficient. Paid me top dollar for my trade in. And gave me a very fair price on their bmw M5. Thanks for getting me my dream car at only 6% when everyone else was at 12% finance gurus will send my people to you Nick!

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.

My vehicles have been serviced here since 2009 and as always quality work was performed in a timely manner. My service manager was Andy who was professional and very polite

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!

Eder and Ralphy great dudes great experience with them treated absolutely awesome form the moment I walked in…. Definitely will be sending friends and family their way… again awesome experience

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.

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...

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.

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.

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.

Dominick was very patient with me and had a wonderful experience buying my third Lincoln from Bright Bay. Everyone at the dealership from the salesman to the worker who greets you at the service are gracious and professional.

Nice and easy. It’s the second car we get here just because the family grew and we needed something bigger. Steven made it a smooth and exciting experience, as it should be. That’s why, at the time to get a new car, we called him back and he (once again) delivered. Very helpful and knowledgeable about cars, had the best advice on what could work for us. Not a pushy, desperate guy and the place looks awesome; very meta and family friendly. My kid was running around all over the place and everybody was very understanding and pleasant. Definitely going back in case we need another car

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.

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

Very kind, professional and most important FAIR! I was extremely stressed over my car situation and it was a weight lifted off my shoulders! Down to earth and extremely understanding! I am very satisfied and will reccomend them to those in need of a vehicle

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.

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.

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.

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

Always take care of theirs customers honest and professional been going there for the last 16 years. Brought a new car last year a 2024 GMC Acadia. Highly recommend them. Travel from Brooklyn for all my services.

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

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.

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.

We recently purchased a 2017 Toyota Highlander from Toyota of Massapequa, and the experience was absolutely outstanding from start to finish! From the moment we walked in, our sales representative Nomaan made us feel comfortable and respected. He was incredibly knowledgeable, attentive, and, most importantly, genuine. We initially came in to look at a specific car, but ended up spotting a few others that were out of our price range. Rather than pushing us toward the more expensive options, Nomaan had an honest conversation with us about what mattered most to us, our budget. He truly listened and helped guide us to the best fit without any pressure. My husband had a question about the brakes, and the team at Toyota of Massapequa didn’t hesitate, they immediately reinspected the vehicle and even resurfaced and replaced the brake pads. That level of transparency and care meant a lot to us. As Nomaan said, “First is the best”, and in our case, the first car we saw in person ended up being the one. We are thrilled with our decision and love our new Highlander! We also worked with George, our financing associate, who did a fantastic job laying everything out clearly and ensuring our monthly payments stayed within budget. Both Nomaan and George were extremely warm and welcoming, it honestly felt like talking with family. Despite arriving close to closing time, we were never rushed, and they both took their time with us like we were their only customers. We’re beyond happy with our purchase and the overall experience. Five stars all the way, we would absolutely recommend Toyota of Massapequa (and especially Nomaan and George) to anyone looking for a car!

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.

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.
