I'm not sure of the dynamics in play, but was wondering why there isn't a formal database hosted somewhere that contains information about about each component for each year/factory/model, with pictures, discussion, debate, etc. It could be done in the form of a WIKI or some other existing open source software.
Is it because there are books to be sold, or that it's just too big of a project, or is it something that just hasn't happened yet?
This is an honest question, not meant to step on any toes.
