Quite. And well, the whole Horch hood ornament thing is unique, if anything. It's oddly gothic-like for me, and I bet Colani had that sort of inspiration behind it as well. Looks like something you'd see at an art gallery (obviously true, I know, but still).
And that last car isn't even that outlandish in design, it's just that the rest look way past any plausible futuristic era. Especially that black "thing" with the orange stripe and the huge hole between the rear wheels... Or the pink car, that looks like what the Thunderbirds car would be if they had used a flamethrower and some Chaparral 2J design sketches to make it.
