Since the OP mentioned the crazy early streamlined design, how about this one?

obvious answer:

Doh! How did the Countache not make this list?!!

Not a plane but it's pretty freaking cool. There is another one of a MEDEVAC bird landing on the roof of a building with it's tail hanging off the edge, but I can't find it.

As a frequent bike rider I hate to see anyone get nailed but, fuck me, this guy was asking for it. He got lucky on the first red light he ran so it was just a matter of time.

Chevy Volt.

That is not 150k.. If it was perfect with no flaws, and from the original batch maybe. That is a fairly early chair, but it is beat up and has been fixed with the wrong hardware... Its not cheap maybe 3k at most if they are very very lucky. You can get a real one new for 700-1,200 depending on material. Copies…
