Used GMC cars for sale near Old Westbury, NY under $899,990

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Thanks to Bill Walsh who managed to get the car detailed the night before and get me in and out before noon on a Saturday. I love it!

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!

It’s been six months since I bought my GMC Terrain here. The car’s great - roomy, comfortable, easy to drive. I use their service center regularly. Staff are friendly and parts are genuine, but brake disc replacement seems a bit pricey. Might compare next time.

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

Slightly disappointed: I wanted a specific Yukon trim that was listed online, but by the time I arrived, it was already sold. The manager Ken apologized, offered another option and a service discount. Fair enough, though I wish listings updated faster.

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!

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 always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Only problem. They praise. My car too low. If they raise my car appraisal. I will make a deal.

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.

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

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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.

25 000 miles on it so far No issues at all Power is fine Bluetooth is terrible Memory seats need work Lumbar is a bad design

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!!

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

Jim Kelly is an excellent salesman. We went to buy a pre-owned XT5 or XT6 and he was so patient with us and just made the whole experience a Real Pleasure.

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!

Estamos muito felizes com nosso carro muito confortável muita seguro . Dar confiança ao motorista espaço bom para minha família eu minha esposa e dois filhos

Upon first impression I wasn’t sure how this was going to go. There was no receptionist and there was no organization as to who to speak to once I got there. But once I was placed with my sales manager Alex, the experience became a different story. He was helpful, professional, but very real. He didn’t xxxxxxxx, lie, or act like he knew things he didn’t, which I appreciate! Even though I was liking at a used Ford he didn’t try to sell me in something I didn’t want. He just gave his honest opinions and knowledge to help me make my decision. I didn’t buy right away, which was actually encouraged by him, to see the other vehicle I had in mind. Even gave me tips on what to look for when seeing other used vehicles, which was welcomed. After viewing the other vehicle and having the exact opposite experience with a local Ford dealer, I chose to go with car at Toyota of Hackensack even without an CPO certification, simply because I just trusted them more, they were upfront with all the costs. Alex didn’t try to slip anything by me when we sat down for pricing. The price was exactly what I expected to pay given the sticker price. I was assisted with getting a great rate on insurance by the dealership, and the finance guy Steve was just as helpful and easy to work with. They matched a finance rate I was approved for by another bank. Steve didn’t hard sell me on an extended warranty, but explained everything pretty well and gave me time to think and research. Overall I came away with a very good experience and so far, a great car. I would definitely recommend dealing with Alex and Steve at Toyota of Hackensack!

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

Salesperson was very helpful, the problem was transporting the car from NJ to KS. May recheck!

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

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.

Taking it on road trip Oklahoma to Key West Florida w/ stopover in Tennessee. I am getting 30 mpg running 75 mph. It handled like a dream going through Smokie mt. I was getting 32 mpg there. I like the ride on the interstates & I love the adaptive cruise control.

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

Routine maintenance was fast and hassle free would come back again for service. However, the sales team could learn a lot from the service team in terms of professionalism, timeliness and good service. Service Team A+ , Sales Team F-

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

I am happy to announce that the dealership and I have finally called it a day. I worked with Martin. We discussed and settled on reasonable grounds. I am simply glad that the matter has been resolved, it’s over and now we can put this behind us.

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.

Deborah was very accommodating and easy to deal with. She was straight forward, nothing more and we got a good deal. Jonathan, the Manager was also very helpful and accommodating. And so with Eric, one of their salesmen

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.
