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

Great experience. Very knowledgeable and worked with me to find my perfect car. Will definitely be coming back!

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!

Transaction was very smooth from start to finish. Sales staff was very professional, especially Greg and Joseph who were very responsive.

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

Good Service!!!!!, and I will have the car serviced again in the future in the same facility!! The Service Manager was a professional as far as his approach was concerned!!!

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

They sold me a 2024 Honda Accord. Window sticker brand new was $36,000. After their fees (Which they did have guys) taxes, dmv and state fees.. we ended up paying $33,000. $3K more than originally listed price. This is still a fair deal. The vehicle had 1.5K miles only on it. Therefore, i am ok with saving $3K-$5K all day. Because new car would have been window sticker plus tax etc. also they are very friendly. The guy in the front knows how to work magic

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

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

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!

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.

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 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!

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.

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 was very extremely happy with the service I received. The salesman Paul was very professional and didn’t pressure me.

I was very suprised with the gas mileage at 21mpg highway,I was use to 11mpg with my 2000 GMC 3500, I got 500,000 miles plus from my old van and still running strong, I hope the same for this one

See Will for the best sales service. He gets to the point and he’s super friendly!

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

It was my best experience. Now, i can say that the money is well spent.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

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

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.

Exceptional Service and Dedication at DARCARS Lexus of Greenwich! I recently purchased a car from DARCARS Lexus of Greenwich, and I can’t speak highly enough about the exceptional service I received. From the moment I arrived, the team made me feel valued and ensured every detail was handled with care. A special thank you to Brooke Jessup-Labonte, who truly went the extra mile—literally. When I decided to sell my old car through CarMax, Brooke offered to drive it back to my home, spending over several hours in unexpected heavy traffic. When an issue arose with the payoff information, he handled it seamlessly, contacting the dealership and Toyota to resolve everything on the spot. His kindness, patience, and professionalism left a lasting impression. I also want to recognize the incredible teamwork of Dave Miller (Manager), Andreas Tsirikos (GM), and Michael Tuzzio (Manager). Together, they made what is often a stressful process feel smooth, efficient, and even enjoyable. I’m absolutely thrilled with my new car—a Lexus that I instantly fell in love with during my visit. It’s a perfect fit for my needs, and I’m grateful to the team for helping make it happen. If you’re looking for a dealership that values its customers, provides impeccable service, and goes above and beyond, I highly recommend DARCARS Lexus of Greenwich. Their dedication and care made this an unforgettable experience, and I wouldn’t hesitate to recommend them to friends and family.

great styling and interior. nice features and acceptable performance. overall my Denali is a superior product to similar vehicles. I would recommend this GMC Acadia.

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 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.

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.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

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!!

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Great customer service Paul and Rich get you the car you want guaranteed and good condition

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

I bought 2 cars in late December, 2015. There was also a trade-in on one of the purchases. In both instances, and on all accounts, including maintenance service since then, I would highly recommend D&P. Phil is an excellent individual to interact with, as well as all the staff. Nothing is complete unless Phil agrees, and his method and mode of business are excellent. His philosophy of selling cars in based on total satisfaction. Everything is performed on a car for sale with the idea that the buyer will not have unexpected necessities for at least a year, or more on very low mileage cars. I recommend D&P without qualification.

Tons of room , plenty power , very fancy and high tech for a truck worth every dollar and look very nice on the outside

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.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

they were perfect, they waited for us and everything was perfect! jeff was the man and make sure you guys talk to him!
