Used GMC cars for sale near Port Jefferson, NY

Always friendly and honest service. I bought a CPO Escape from Stamford Ford a number of years ago. There was a stupid problem with Ford Credit - it was enough to make me cancel the order. When Dominic found out about it, he called Ford Credit and told them to get it right. They did, and Dominic called me back and made the deal happen! Since then, Ive been bringing my Escape to them for service. They are reliable, friendly, and HONEST. Scott Ferrara in service is THE BEST! I noticed a number of reviews with regards to lack of communication while vehicle is in service, especially having a person answer the phone. This appears to have started since Covid. I'm guessing that it is because it seems harder to get good help these days. This is not unique to any dealership or brand. In fact, I have another brand of car that I bring to another dealership. By comparison, this other dealer does not deserve to clean the floors at Stamford Ford. The service advisors at Stamford Ford provide you with a cell phone # you can text if you need to, which is a lot easier than getting though via phone. Again shout out to Scott in Service!!

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!

We dealt with Howie. He was very personable and easy to talk with. He made the whole sale quick and easy. Thank you for an easy experience.

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.

I visited on the second day being opened and had a great experience in buying a 2022 Explorer and trading in a 2016. It was seamless. Had an issue with the new car that turned out to be a factory defect that they had Ford correct. All good. I’ll be back.

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!

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

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

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

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

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!

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

Laurie Dunn was a pleasure working with while the dealership was fixing my SUV, she kept me UpToDate with what was going on. All in all, everyone I spoke to while at the dealership was very helpful from the showroom members to service even the valet guy.

I had an exceptional experience at Minchin GMC in Stamford, CT thanks to Chris. From the moment I walked in, they were friendly, professional, and truly attentive to my needs. Chris took the time to understand what I was looking for in a car and guided me through the entire process with patience and care. They answered all my questions thoroughly and helped me find the perfect vehicle that suited my preferences and budget. The entire purchasing process was smooth, and I never felt rushed or pressured. I highly recommend Chris if you're looking for top-notch service and an easy, stress-free car-buying experience. Thank you again, Chris, for your outstanding help!

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...

Very friendly, enjoyed the conversation! We are our of towners, gave us advice on what to do and visit while in town.

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.

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

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.

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.

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

Excellent communication. Very responsive and provided detailed info. They answered all my questions via email and offered to call.

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.

Folks were very nice. Just did not find the right car there. Test drove a couple cars but none worked out for what I was looking for.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

It was great experience buying car here today at key hyundai milford. We received the best customer service highly recommended!!!

We just purchased a Tahoe High country from Paul C and we absolutely love it. This is the third vehicle in 5 years from Paul C and it has been the best experience we have had at any dealership. The management and finance were also the best we ever worked with.

On March 25, 2025, my EXCELLENT 2024 Buick Envista received maintenance service at Arnold Chevrolet Buick in West Babylon, N.Y. Service advisor, Gregory Silano, was friendly, knowledgeable, attentive, and efficient. The work was performed expertly with a short wait time. Scheduling a convenient appointment was quick and easy. Arnold Chevrolet Buick in West Babylon, N.Y. is the BEST dealership, with the very best sales, automobile service, and customer service associates. I highly recommend Arnold Chevrolet Buick in West Babylon, N.Y 11704

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

I arrived knowing the used car I wanted to buy. I had been following the posted ads for this car and was concerned about the pricing changes, first down and then up for a couple of times. There is no negotiating the price since I had no trade. The financing was done professionally. My salesperson was super nice and instrumental in the registration and changing insurance.

I love the Yukon. It needs a few censors changed out but it drives so smooth. Very glad we made the choice to purchase it

Excellent service and wonderful experience. A pleasant experience. The salesperson made us feel very comfortable

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

I always receive prompt and courteous service every time I visit Arnold Chevrolet. I have serviced my car here since I purchased it from this dealer several years ago.
