Nervous first time buyer
My mom wanted to purchase her first ever car, but was extremely anxious & nervous about the process. Greg made all her anxiety & nervousness disappear. He took his time & explained everything to her, sometimes numerous times until she was comfortable and understood everything. He is truly a credit to his chosen career & if I may say so, humanity. I would not hesitate recommending Greg to anyone who asked if I knew a trustworthy salesperson in the car dealership world.
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.

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
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
We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

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!
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.

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. 👍
