I was concerned about going to an out of state
I was concerned about going to an out of state dealership, but I was impressed with your high customer service ratings from customers. I felt they were very professional and while pushing us to make a decision, they weren't obnoxious about it. In the end I thought they gave us a fair deal and we love the SUV. I would have no problem making the trip to Massapequa to buy another car.
This truck has a jerk when changing gears sometimes.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

New car purchase
My husband and myself went to East Hills looking for a 2022 Equinox our salesman was George. I can't say enough about him, he didn't force us into anything and worked with us to keep in our budget. If you need a new car go to East Hills and ask for George!!!!!!
I have owned 3 yukons
I just purchased a 2024 Yukon Denali XL. This is my 3rd Yukon. So needless to say I am sold on this style of vehicle. The style and comfort are impeccable. Had a 2009, 2019 and now a 2024 XL. Never had any problems.

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?

2022 GMC Sierra SLT 3.0 Duramax
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!

Pleased that I made this purchase
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.

Best experience buying a vehicle!
My husband purchased a truck a few weeks ago from JTL in selden and it was the best experience we’ve had at any dealership in years. Everyone there was patient and really accommodating, we had some hiccups while getting approved for a loan but they helped us in any way they could, all while making sure we were still comfortable with the payments we’d have to make. The truck is exactly what my husband wanted and everything about this process was amazing, thank you JTL!
Glad I switched from a car to a truck!
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!

No worries...
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.

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.
