The Slate only tows 2000lbs, and has a tiny bed. If you need a truck it isn't for you. Maybe it works as a SUV.
Of course most people only need a coupe to begin with. Too bad you can't buy any that are cheap. (that and you mostly only need a coupe, but at least once a week need something more)
I bought a house recently, and need something to haul landscape stuff around. Slate is perfect for that. I also need something to haul wood around for woodworking etc. Slate is perfect. If I need to help my kids move out of their apartment or move some furniture, this is perfect. Can't do any of that with my coupe.
And the Slate should have better utility, for anybody who needs a truck/SUV vs coupe. And also comes without the Musk stigma.
