When the boom in muscle car buying dies off, and the high prices the market is suporting now drop significantly, what do you think is going to happen?  

I'm not sure, but the word "display" comes to mind.  

I don't know if these guys can afford to have these cars sitting around on display. And since most of these "collectors" stash the cars in garages where they're never seen or driven again, I don't see displaying as an option.
