It’s mind-boggling. You sit there for hours, watching middle-aged guys in Hawaiian shirts and big watches bid stupid money on muscle cars on the myriad cable channels that broadcast collector-car auctions these days.

That’s in the millions: A 1967 L88 Corvette went for $3.5 million at Barrett-Jackson—before all the fees that make founder Craig Jackson wealthy.
