Steve McQueen's cars go for big bucks

This bike sold for 24 times its ordinary retail value. Now there's a mark-up. This one-cylinder Swedish-made off-road bike was known for its light weight and big power but it was considered difficult to ride.

When the price of a vehicle gets this far from the machine's inherent value, you might wonder whether its worth won't drop just as precipitously as time passes and people begin to forget this McQueen fellow.

Corky Coker, whose company, Coker Tires, supplies tires for antique and collector cars, doesn't think the luster will fade. Once collectors have established a certain value for McQueen's cars it's not likely future collectors will change their minds.

"There's a likelihood it will taper off at some point," Coker said, "but I don't think it will ever go away."
