What year release of a bike is too old for a bike?

[CitedOrange1]

Hi, I've got a question, what release year of a bike is too old to buy used, for example if the bike is 2007 or 2005.

well that really depends on how the previous owner has treated the bike, I have seen bikes from 2004 which where in a much better state as bikes from 2011
