Quite a subjective term, this 'Classic & Vintage'.

For example, if you follow the 25+ year criteria then any bicycle from 1987 or earlier would be considered C & V, right? But within that range there's some gray area there. I'd consider a 1984 Miyata 710 as C & V, but not an '84 Nishiki Sport. An '87 Miyata Ridge Runner SE... yes. An '86 Giant AT 750, yes. An '87 Nishiki Backwoods... no. An '88 Panasonic Sport 500... no.

So, I think it's depending on the type of bike you like, and whether or not it's unique enough to call it classic or vintage.
