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
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.

Curry Chevrolet is the ONLY dealer to use!!!!
Going to Curry Chevrolet is like going home to family. Everyone takes care of you. My salesman, Danny, was invaluable when it came to matching all my needs, going to get my new Chevy from Canada and showing me all the fancy features at the day of delivery. Mike Crispinelli, general salesman, was someone who basically moved heaven and earth to get me the car of my dreams. Boy can he come through when it looked like all was lost. Marsha Ashley, finance manager, couldn?t have made the purchase any smoother or easier to go through. Last car, she gave me such good advice for purchasing an extra warranty package. I can?t tell you how many times I thanked her in my head! This time around, that was my first question- do they still have the extra warranty? The answer was yes!!! Purchased that with no hesitation. Marsha really looks out for the customer?s best interest. Let?s not forget to mention Dirk Miller, service advisor, who will always fit you in and make sure your vehicle is running smoothly. He was instrumental in getting my running boards on so I could pick the car up a day early. On another occasion, he gave me his personal cell phone number to help me with a flat tire situation. Tire was unavailable and he told me to call him if I got stuck and he would send the Calvary. It was such piece of mind but thank goodness the tire lasted for one more day. What employee would do this for a customer? He?s a true gentleman and gracious example of how people should treat others! I?m sooooooo happy with Cury. I always brag about my gem of a dealership!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

I had a very good experience with Dione He was very helpful and answered my questions within minutes. Car was given to us with a full tank of gas and it was an overall positive experience
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.
