They had white, silver, granite, and black. I really liked the white the best. The contrast just really looked good to me. Plus, white is very forgiving for scratches and swirls, and it doesn't get nearly as hot sitting in a parking lot during the summer.
I'm still interested in knowing exactly what it is going to look like, I've seen the supposedly leaked pictures of it of what the 2020 line up is going to look like. Though the surprising thing is I have not seen any Test Mule Spy Shots! Not a single one. Almost 5 years and you can't tell me nobody has seen a Test Mule out there on the streets. When I used to drive I saw Test Mules all over the interstate highways. This also includes back in 2008 a Mustang being tested with IRS.
