$100 Million for a 2009 Mercedes CLK-Class?

I was looking at the car prices on EBay, and some of them make no sense at all. They had a 2009 Mercedes Benz CLK-Class that was up for bidding, and the supposed "bidders" had raised the price up to $99,999,999.00!!! Now I'm curious to know what's behind these supposed "listings" that doesn't seem real and that do reflect a price that's way beyond the actual market price. And what about the highest "bidders" that do not seem to be actual actual individuals..? Does anybody have a clue of what is the purpose of these crazy listings?
Here is the actual item that I'm talking about:
