Love my sportage!
We were greeted with a smiling face from Gerard. He answered all our questions. Took us to see cars available, but I got attached to the s portage parked outside. He treated us so nice. No pressure. Said, if we need anything, don’t hesitate to call or come in. It was a great experience.
Stylish and comfortable.
Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

Wow what a complete difference in professional service
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.
Looked at more expensive truck with less options, bought
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 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

Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Great experience!
James is absolutely amazing. He made it quick and painless! I’ve already recommended several friends to James Boyd and Hyundai route 112!
Surprised myself and bought a GMC
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.

Favorite car I have owned, to date!
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!

Awesome trucks
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 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?

Great purchase experience
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.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Great deal.
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.
I have owned my Acadia just under one year.
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.

Buying my Buick was a great experience, they give you
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!!
Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family
