Used GMC cars for sale near Copiague, NY

I recently had a wonderful experience at Mazda 112. My sales person Bonnie was amazing. Bonnie was extremely knowledgeable, friendly, professional and helpful. She answered all my questions, listened to what I needed and wanted, and put me in the perfect vehicle!

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

Their ratings are high because it is definitely well deserved usually I would be skeptic thinking it would be many fake reviews but after our own experience at Hillside Toyota their reviews are truly legit!!! Their cars, trucks are amazing. Their customer service especially the one who helped us whose name is Valentina is excellent, professional, helpful and she is so cool. Any questions we had was answered. Anything we did not understand she went beyond to help us from beginning to end. Definitely ask for her for above and beyond service and assistance. On top of that first day got some awesome yummy popcorn and the last day bagels and coffee. We are new to the new technologies in our truck and she explained everything and even set up everything for us. Thank you Valentina and Hillside Toyota.

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.

My review is about Paul Whaley; i have only good things to say about him. Paul is a young man, very respectful, professional, attentive. He is very patience young man and always in contact with me without put pressure on me .Thanks Paul for all your efforts to close this deal, and I hope we do it.

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.

I bought a 2022 Escalade ESV in 10/2023. From start to finish there was no hassle I saw the vehicle and did not purchase for over 2 months shopping around for a better deal. I went to many Cadillac Dealers across Long Island and they did not take me seriously. When I told them what I wanted my payments to be they didn't even attempt to really search for a vehicle that could match my interests. This Dealership allowed me to test drive without prejudice and also were totally patient until I was finally able to clear title problems with my Credit Unions because of NY State Laws and then Finance with Cadillac. I was shown the vehicle features several times to at least get the vehicle off the lot. My payment was 1265.00.. but now I'm down to 1065.00 per month. I would recommend this Delearship to anyone in the world. They go above and beyond in Customer Service.

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.

I?ve been bringing my truck to the Rockville Centre GMC service department three or four times since purchasing it in 2021, and every visit has been a great experience. The entire service staff is amazing?professional, friendly, and genuinely helpful. The service manager is always around, easy to reach, and makes sure everything runs smoothly. I?m very glad I bought my truck from these guys. It?s a great local dealership, and I highly recommend their service department.

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.

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.

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!

The service was done well. Dominic was a professional and did a great job putting everything together.

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!

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

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

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.

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.

Kevin has been an incredible sales person. One of the best I’ve ever had will continue to business with them.

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.

Chris Castillo and Orlando Zayas were extremely professional and helpful. They made the car buying process easy. Chris was extremely patient and knowledgeable. Orlando went out of his way to make it all work. Thank you!

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?

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

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.

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 bought a Cadillac CTS2013 the staff was great and my car is beautiful I love it .I would recommend this dealership to my friends

Awesome car! Reliable and I have 200,000 miles on mine and never had a major repair. Comfortable. Good for towing. Easy to hold a lot of people. Speaker quality is good. I’ve owned about 6 different cars and this is my favorite by far.

First off I would recommend this dealership to all my friends.. I went in to purchase a 2016 maxima from the minute I got in… Rehan was on it he made me felt at home not pushy was great with me my credit wasn’t so great and he help me get the car with no haggle… thanks Rehan we will see u soon for our next one.

Great selection found my 2019 Honda Odyssey there the sales rep was great the manager was cool and the finance lady was excellent I had a overall good time with my purchase I recommend all who are looking for a new car check them out you might find the right car for you

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)

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

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.

Everything was wonderful and great, My salesman Daryl was fantastic and easy to work with, no pressure at all. Everything was easy, my only concern was I had to pay a 3% surcharge on a $1,500 charge which was really a hold until my old title was found which it was, so I had to pay $45 on a hold that only lasted 18 hours being I found my title.
