Used GMC cars for sale near Port Jefferson Station, NY

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

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.

Lorraine was great ! She was very thorough and honest thank you. This will forever be my service department;)

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

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.

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

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

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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.

Excelente atención por parte de Steven, muy recursivo y encuentra soluciones para el cliente

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Excelente servicio , muy amables AJ muy amable fue una experiencia excelente. Good, very happy. Thank you

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.

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!

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.

Buying a vehicle from Jayware was the smoothest transaction that I have ever encountered. No dealer fees, no hidden costs, just straight forward pricing. Awesome job they did.

This Yukon is very roomy, comfortable, has tv for my kids. New tires, great condition Best vehicle I have ever owned. I highly recommend it.

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 exactly what I was looking for! Very well kept and in great condition. Great ride and interior is like new for this 2013 Yukon. All the comfort and space I was looking for to get ready for the winter!

Very professional polite and excellent service. would recommend it to anyone.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Quick and easy beginning to end. I saw vehicle online the price was good and drove it off same day. highly recommend this dealership. thanks colley

Will was our salesperson and I would tell you hands down to just go straight to him. If they have the car you are looking for he will make sure you go home with it that day. Very personable and at no time did I doubt I would get the deal I needed.!

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.

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!

Dealt with Billy, sales manager, Frank, salesperson, and Dennis, finance-person. Professional and honest (all three). We drove 3 - 4 hours from Connecticut to see a 2018, Ford Edge, SEL. Of course, I called for it’s availability. After speaking with Billy, he advised me to think it over before taking such a long drive, however, he will gladly hold the vehicle for 4 hours without any strings attached. He asked that I call him, if I changed my mind from the drive so he can sell the car if needed be. He promised that the car will be available for my family. We took the journey! We arrived 4 hours later. The car was there! Met Billy. He immediately introduced us to Frank. Frank was ready, kind, and professional. Catered to my family and trusted us with car. After 30-45 minutes of test driving. We came back, ready to “negotiate”. Ready, to go “back-and-forth” with the sales people. Ready, to hear the “hidden fees”. We met with Frank, and guess what?! No dealer fees! No doc fees! The price you see, that’s it! We even got a discount on the vehicle! Yes, in this market! We got a discount! We bought the car. Met Dennis, the finance guy, took care of everything. WOW!!! Everything went smooth. Professionalism and Honesty. Thank you Stevens 112 FORD of Patchougue, Long Island in New York.

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.

Great service, she let me know all the way through the process and it was a very nice experience

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Great Experience!!! Smooth process, Lorena was awesome, excellent value, stress free pickup, highly recommend to go see Lorena.

Probably one of the best car buying experiences ever. They showed me the car I was first looking at then 1-2 more options. I ended up going with one of the alt. options that actually had better equipment but at the same price.

Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Great experience as always! Mike Perez and Mark Ospina always treat us like family when we come in. 4th purchase from town and country and counting

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.
