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!!!!!!
GMC Acadia good family or commuter car
Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .

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.
Love my GMC Terrain!
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.

Worked with me the whole way to get my car serviced when my car engine seized stemming from a recall. They provided me a loaner until the part was sent from the GMC main warehouse.
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.

Diesel AT4 it!
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!

Overall Great Truck
I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Bought my 2018 4Runner from them. Good "No haggle" price. In spite of the "Covid" restrictions the process went smoothly. Their "Detail Center" was closed due to the restrictions so they gave me a "We owe" on the cleaning and detail.

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

Hummer EV Production Delay Eroding Hummer Advantag
Currently, the Hummer EV is a decent electric vehicle option. However, as newer electric vehicles, especially the Cybertruck, are released to the market with longer range and cutting-edge features at a lower price point, the Hummer EV will fall behind. The Cybertruck is anticipated to enter mass production later this year, while GMC's production is slow, putting them at risk of falling behind competitors who may enter the market with newer and better offerings by the time GMC's product is ready for a refresh. Although GMC initially released a good retrofit product, their production delays are gradually eroding the Hummer's competitive advantage.

My new 2023 Kia Forte
I thought was very professional and knowledgeable. Chad was my car salesman for my new 2023 Kia Forte. Chad was very professional and knowledgable. I will always reccomend Smithtown Kia to all of my friends.
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.
