The red car traditionally posted is one of Jeff Keacher'* two red Bonnevilles that he used to own. The first was totalled horribly by an idiot (not Jeff) and the second was sold for a BMW (curses on the boss).
In other words, it'* Jeff'* Forum, so it'* his car. I know this has been suggested before, including the COTM thing, but Jeff prefers to (or at least did then) keep his old faithful up there in the corner.
Chad Vollmer and Peter were rare exceptions.
