"Buyers must do their own Homework"

In general I fully agree with this statement and I'm not taking sides with anyone when I say this,but what homework could a buyer like this have done to find out what he later discovered in his garage before he bid on it?
Are there people out there who knew something about this particular Camaro already?
If so,where are they and would they've spoken up in this day & age without fear of being sued/outed by another?
Do any auction houses allow perspective buyers to take cars apart before they drive them out on stage?
