Maybe vagueposting a little bit, but my personal litmus test for someone's opinions re: cars is The Alfa Romeo SZ. In short: if you don't think this thing's cool as spit, we probably ain't gonna be friends. Shit still looks like the future, man. C'mon.
There's an even wackier Alfa which seeing SZ just reminded me of.
The one-off coachbuilt Alfa Romeo Castagna Vittoria from 1995. I think it's built on the same bones as the SZ, but turns up the freak factor by a pretty high margin. I like it.
