Depends upon your perspective. It's all tied in with age and social history.
50's/60's Americana is a fashion, pre-war vintage a snob fashion. 70's slowly evolving into cool rather than naff.

2020 is the Doomsday date according to Euro emissions of course, and will dictate the future of vehicle propulsion means.
Enjoy while ye may..
