Used GMC cars for sale near Oyster Bay Cove, NY under $899,990

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!

Experience was very nice. A girl helped me. Not sure of her name but she was extremely helpful. Diane Meyer

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!

I always enter a new dealership with hesitation; will they have integrity while conducting sales, or be xxxxxxxx going for the quick buck? East Hills was great to work with: clearly a professional and efficient dealership and Paul Whaley, my salesperson, was incredibly thorough in answering my questions and fully accommodating, but never pushy. Karen Rose in Financing was just as through, accommodating and patient with my questions and her pup, Mia, was a joy to meet. Raul, not my salesperson, made for very pleasant conversation during my wait. While I just purchased my car, I've no barometer to guage long-term support/customer care, but I've no worries that East Hills will be just as accommodating (and if not, I'll update this review). When it's time for my new truck, I'll surely return.

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 a great experience at Generation Buick GMC with Joe Rossetti. He met all my needs, I will be recommending all of my friends.

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 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

Had a great experience trading in and buying newer car. Staff were very professional and efficient at closing the deal.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

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

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

I was impressed of the experience I had with Bomnin Chevy. They were transparent and Jonathan C made it easy for me.

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

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!

My vehicles have been serviced here since 2009 and as always quality work was performed in a timely manner. My service manager was Andy who was professional and very polite

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.

I had an awesome experience dealing with Jonathan C. He made it really easy for me to buy my car.

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.

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

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.

Always take care of theirs customers honest and professional been going there for the last 16 years. Brought a new car last year a 2024 GMC Acadia. Highly recommend them. Travel from Brooklyn for all my services.

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.

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.

Everyone was nice and communicated well. It was easy to work in the service lounge and I enjoyed the coffee there. I would schedule more service here in the future.

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.

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.

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!!

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Excellent Service, Asking Price Was The Price I Paid No Hidden Nonsense Like The Rest.

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
