I knew the AMC line would be mentioned in this thread. So many cars, almost deliberately ugly...wonder if someone was putting acid in the water supply at the deisgn dept?
OTOH, some vehicles are almost admirably ugly. As if, like a disturbing painting, they force one's attention upon them...and, as such, serve a purpose.
To that end, I've always found the early D-series Dodge P/Us to be inspiringly ugly...wouldn't mind owning one with the slant-six!
