Used GMC Sierra 1500 trucks for sale near Riverhead, NY

Vehicle was sold before I was able to speak to a sales person. No problem! They were working on it before I inquired about it.

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

They was very nice an friendly service was great an they made sure I got my vehicle I came there for 👍🏾

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!

I am a repeat customer. There is no other place I would buy a used vehicle. Chip was more than generous with my trade in allowance. The lady that set up my financing, Sam, was a huge help. Great Place!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

I got my first truck here. Will definitely buying from here again. Straight forward pricing! Very knowledgeable.

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

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

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!

Wow, I truly can't say enough good things about this dealership. My first experience buying a car at another dealership was horrible and left an awful taste in my mouth. However, Blasius South was completely different. Jay, Dejon, and Ross made the process painless. They always had a smile, went above and beyond to help, and were extremely open and transparent! I didn't think I would ever have a good experience buying a car, let alone a GREAT experience. I am truly thankful and will continue recommending them to friends and family! 10/10.

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.

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 LOVE YOU JENNY SCHEELE! Does that say enough? Lol. When I worked with Jenny on getting my 17 Explorer last summer I wasn’t expecting to see her until 2020.. I was in a small fender bender that to my surprise was deemed a total loss a year later! If you saw it you’d never think it was either. The moment I got the news I was so upset I called Jenny as I didn’t know what to do.. “Don’t worry we gotcha girl” is what I can remember hearing..I clearly saw her face as she said it too.. If you know her then you know the look ;) Fast forward less than a week later she introduced me to my new 18 Explorer Limited which had everything I wanted and more.. Jenny made a stressful moment for me feel like it never happened and as if it were 2020 and we were going onto my next vehicle. She was there to answer any of my questions I had, which there were many (I would even refer to myself as the “Pain in the a**”), she even answered after her work hours which goes above and beyond the call of duty.. Jenny is awesome and an asset to Ford/Stevens 112 Ford! Again I LOVE YOU JENNY SCHEELE.. see you when it’s time for my Bronco lol... and this is why I am a Steven’s 112 Ford “Lifer”!

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.

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.

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

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.

The dealer was great. But the apple play in my 2024 Sierra is not yet supported. What the xxxx is that about? How the heck can you sell an incomplete vehicle? I?d like to know when it will be fixed. And it better be soon.

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.

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

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.

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.

Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

Buying my Buick was a great experience, they give you time to breath while looking around then approach for help and answer questions! Service area is alway great, always work with you to get the appointment you need! Will be leasing my next car from them for sure!!

Great experience all around, gave me a a fair trade in valve, would highly recommend.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

I have to say this was a great first time experience for me and my family. Rich is the best he made us feel like family he knew exactly what we need. The guys in the office were just as nice. Our family now has a great car that's just perfect for us. The whole presses was painless thanks to everyone's help. The only thing missing was a Sunday dinner. I would recommend Rich and the guys to anyone I care about. I can't wait to do business with them again. The best around.

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.

So i walk into sound auto and was greeted by my salesman Angelo. He is the best hands down. He was committed to putting in my car that i wanted so desperately. He promised me that he is gonna get me that car.He did just that! The very next day i got the call..And he helped me in every possible way to direct me through things.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

They made sure the car that we wanted was road ready and safe for my family. Even after purchase they still are wonderful to interact with. I highly recommend them especially George, he goes above and beyond. We will definitely be return customers 😀

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me
