Used GMC cars for sale near Harbor Isle, NY

We had a great experience overall, especially with Tom. He was helpful from start to finish and we really appreciated how quickly he was able to get us into the car we wanted. The only area for improvement is the final business/finance step. The discussion of additional products felt more pressured than I expected, and I’d prefer those options be introduced earlier so the pickup feels more celebratory.

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.

October 26, 2025, my car needed scheduled maintenance, which included oil change, new filter, tire rotation, and multipoint inspection. As always, Arnold Chevrolet Buick dealership service department was excellent. It was easy to schedule an appointment time that was convenient for me. The advisor, Brandon Coraci, was friendly, welcoming, knowledgeable, and efficient. My wait time in the clean and comfortable waiting room was short. All the service was performed expertly. I have purchased/leased 6 vehicles from Arnold Chevrolet Buick dealership. I have only had the Arnold Chevrolet Buick dealership service department do service on my cars. For 25 years, I have been, and I continue to be, very happy with the sales and service departments at Arnold Chevrolet Buick dealership of West Babylon. I highly recommend this dealership.

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!

I had the pleasure of working with Jesse. He was very professional and extremely patient. He took the time to answer my questions without Casting judgment are thinking that any question was not important. He was able to relate well and made me feel comfortable and at home. I would definitely recommend this dealership and especially Jesse to family and friends. I had visited other dealerships prior to Metro Honda and did not feel as if I was taken seriously. We are extremely happy with our purchase.

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

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

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.

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

Took about 3 hours but it was worth it. They were able to purchase and pick up the bulbs to install in the vehicle properly.

The best used car purchase I’ve ever had. It was easy, simple, and straight forward.

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.

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

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

AJ salesperson was amazing, got the car i wanted, had to wait 2 days but it was worth it. Lots of love for nissan of Westbury, and thank you so much AJ

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!

Have been doing business with this company for at least 15 years. I find them to be reliable and trustworthy.

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.

I purchased a 2026 Equinox from Mr Tom LoBue, who was professional & courteous through the process & made sure I got the vehicle that I wanted. Thank you.

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.

This visit was to purchase our 5th new vehicle.It?s always a pleasure to shop here. The sales person is always very knowledgeable about the vehicle.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

My experience start to finish was nothing short of excellent. I live in Wyoming and saw a car I’d been searching for for many months. I was a little hesitant to buy at a distance sight unseen but from the first call I received nothing but transparency and honesty. I requested some up close photos and video walk around. I got that shortly after my request, and in amazing detail! Mike was honest and forthright and answered all my questions with patience and respect. I’ve never bought a car at a distance before but I can say that I am extremely pleased with my new car. It was well described, and honestly arrived in better than I expected. It is a used car but the quality and attention to detail shows better in person than did in the photos! Mike was more than up front about the car do , where it came from, its history, the condition, and managed my expectations better than I thought possible. This is a first class establishment and I am really happy with my purchase. I’m glad I took the leap of faith working at a distance, I admit I was very hesitant initially. I got the car I wanted at the right price and all without leaving my home. I strongly recommend you give Kings Point Auto a try on your next purchase, even if buying sight unseen like I did. They did right by me at a long distance & and I will surely be doing business with them again next time. Thank you Mike & Kings Point Auto! Keep up the great work!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

my experience with akar is fantastic they took real good care of me Ehab and Joe are the best and found the right car for me i have been going to them for my oil changes and bought my saturn from them outside of brakes and oil changes i never had a problem the car unfortunatly was in a accident and totalled

I love it so much lots of space .. every thing clean no dents or scratches every thing is perfect all everything fully loaded the best

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

Scott Yager and his team worked night and day to get the best possible deal for the vehicle I was looking for. This is the second vehicle I have purchased from autoworld Kia The sales and service personnel due their best to get and keep you on the road

I recently purchased a 2023 BMW X5 from Island Auto Group, and the experience was outstanding from start to finish. I’ve bought and leased several vehicles over the years, and this was easily one of the smoothest, most transparent car-buying processes I’ve had. From the moment I arrived, the team was professional, knowledgeable, and respectful of my time. There was no pressure, no games, and no hidden fees, which is something I really appreciated. They walked me through the details of the BMW X5, answered all my questions clearly, and made sure I understood every option before moving forward. The pricing was fair and competitive, and they were upfront about everything — trade-in value, financing, and next steps. The vehicle itself was in excellent condition, exactly as advertised, and the delivery process was seamless. What really stood out was the customer-first approach. It felt like they genuinely wanted to earn my business, not just close a deal. The entire process was efficient, professional, and stress-free. If you’re looking to buy a pre-owned luxury vehicle like a BMW X5, or honestly any car, I highly recommend Island Auto Group. They made what can be a complicated process feel easy and straightforward. I would absolutely buy from them again.

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. :)

Excellent service. Ask for Delano Ashmeade. Smoothest and easiest transaction you'll ever experience. A1

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Wow! What a smooth and effortless experience!! I have to give a special shout out to Miguel, who helped my wife and myself buy an amazing used SUV - a beautiful Nissan Rogue full option for a great deal with affordable payment options. He was such an angel. Thank you Miguel. Thank you Magic Auto Sales. You are the best ❤️‍🔥🙏🏽 I recommend this used car dealership for anyone who doesn't want to get ripped off by preying dealers.

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.
