The Hunt for Red (and Blue) Chiron ...

[dr. d]

I had the same question. To weed out joy bidders?

... with a bond of 15 milling bucks... i do not think there will be joy bidders.
i await for them to explain the logic of their policy.
... and should there be no winning approved bid, these cars should be bulldozed over, to assure no hanky-panky.
heh heh.
