Just picked up this new 2020 AT4 over the weekend. Got a smoking deal on it so i couldn't pass it up! It's got the 6.2, Premium package, technology package, driver alert 2 package, sunroof, and the accessory off road steps. I've got an email sent to the dealer asking what happened to my black mirror caps as well. Here's some pics along with it's new garage mates (18 Yukon Denali & 17 GT350).
