Discussion I was having with a design guy from GM: it takes about 20 years for something to become a classic. '70s cars become classics, '80s fashion becomes retro, '70s furniture becomes retromodern. Anything you buy right now is likely to look dated within five years (cars tend to last a little longer), but in another fifteen, you could be making bank, assuming that the car holds up that long. And I think that'd be the biggest thing standing between today's cars and tomorrow's classics: a great many cars today are such absolute crap in terms of construction that they might not survive to become classics, while yesterday's well-preserved '66 GTO will be a superclassic.
