Well I came 31/2 hours to see a car and it’s gone yesterday I wanted it I was buying it because i recked mine i wanted the same thing
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Unbelievable shopping experience!
I had THE best experience at Carmax...the salespeople were non-pressuring, helpful and just amazing (especially Daniel!). They went out of their way to make every step comfortable and unpainful. I will most definitely go there when I need to buy my daughter a car and when I need to upgrade in a few years!
2020 GMC 2500 AT4
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.

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.

Go see Luis at Blasius South.
Go see Luis at Blasius South. He was attentive and very easy to work with. The whole process was perfect start to finish. Everyone there was helpful and very knowledgeable!!
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.

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!

What a pleasure to deal with salesman manager number one
What a pleasure to deal with salesman manager number one Would definitely buy another car from them in the future
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

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!

The sales staff and the management with above and beyond
The sales staff and the management with above and beyond their duties to make sure that my new vehicle purchase went very smooth. Will definitely come back.
So far have loved my 2020 2500 HD 4x4 diesel
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

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. 👍
