Used GMC trucks for sale near Cold Spring Harbor, NY

went there for the first time about 1.5 weeks ago for service - great experience - Emily was amazing...personal yet professional - she stayed in contact with me and kept me updated about the car, every step of the way - highly recommend their services -

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.

Ronny Terraferma was amazing. Treated myself and my daughter like family. He was honest and professional throughout the entire process I will definitely will return for my next car!

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!

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.

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.

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

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.

All of the people I?ve dealt with here have been friendly, helpful, professional, and considerate. Unlike most places here they are quicker than expected to finish what they?re working on for you. The whole facility is clean and the waiting room is very comfortable?roomy w/comfortable chairs, TV, charging ports, coffees, hot chocolate, tea, etc.

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

Been going to same auto mechanic here Steve and this guy is outstanding, he always tries his best and super friendly work is superior and top notch. I wouldnt go anywhere else. Thanks Steve for all your wonderful work.

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

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.

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?

Honestly don’t know where they get so much patience - I recalculated lease payments ten times, changed terms, down payment, and asked a million insurance questions.

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.

Rodrigo is great sales person i buy 3 cars from them good dealer no hiding fees

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.

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++

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...

Tom Cali is an excellent salesman. He is so professional, patient and helpful. We went to buy a pre-owned Lincoln Nautilus or Aviator and he was so patient with us and just made the whole experience a Real Pleasure. We will be recommending everyone we know to go to Bright Bay Lincoln and that is where all of our future purchase will be. Also, Prescott in finance was honest, caring and wonderful too. FANTASTIC EXPERIENCE ! ! !

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.

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

I WENT WITH MY DAUGHTER TO TEST DRIVE A NEW RAV4 AND DEALT WITH KARTIK GULATI.HE WAS VERY PROFESSIONAL,HELPFUL AND POLITE.AFTER TALKING WITH K.G.I BOUGHT A RAV4.I AM IMPRESSED WITH K.G.AND EXPERIENCE AT DEALERSHIP

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.

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 nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Great honest place! I found my car online went in and the price was the same! There were no fake fees and I all in all it was a great experience

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

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 !

Love this place go buy your next car here and not anywhere else at all or you?ll regret it. They have the best deals and the best inventory.

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.
