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.

Illinois Motors Review
Purchased a car from Regis at Illinois Motors in Cary. Car was purchased from out of state . He made the whole process seamless. He took a video of the car and pointed out the only blemish on one of the rims. Regis arranged transportation to my house and the car arrived on time as promised and in the condition as advertised. Could not have been easier and the car is great. Thanks Regis
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.

Keith is the best salesman we have dealt with in our car buying exspeiences. See him my best advise
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.

I went to this place to purchase a 2019 VW Alltrack SEL, Stuart the sales person was very friendly and cooperative. He even went above and beyond. But the sales manager was little stubborn on the price even though they published a SE trim as SEL though it has some additional bells and whistles. I was also in hurry, they helped me move quicker and financing made it quicker even though the interest rate was not that great. But no hidden fees. Overall the experience was great.
Best truck I've ever owned....
Could never buy another truck after owning this. I'm only getting rid of it cause I ordered a 2021. Hands down, this is the best of the best!!

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.
