It would be feasable to "build" a numbers match hemi cuda convertible for that kind of money, so its getting a little weird.
Especially since those cars (cudas) were kind of crappy and lackluster compared to even a regular big block camaro or chevelle.
As was stated earlier by others, the value is in the "idea" of "I have one you don't" inherant to ultra wealthy collectors.
They spend it because they can.
Whats 5 million out of several billion?

Those cars are realistically "worth" probably 250 to 350 thousand though. 5 million is really inflated.
Its kind of like a game of hot potato. At somepoint, someone will be left in the end with a car that no one else is willing to spend the money to get.
