I think them all very stylish to look at, Neptune my friend.
Typical of me with unusual vehicles though, I rather like the little three-wheeler "swollen Messerschmitt Kabinenroller". Next would be the finned hardtop, and then the truck.
Each would make for a very interesting model, to say the least.
I'm certainly going to enjoy watching these vehicles emerge in their various forms.
Kind and Respectful Regards Neptune my friend, Uyraell.
