I know the bidding has ended, but it may come up again as it didn't reach it's reserve. 1st of all I don't sugest you bid on a car without looking at it (unless you just want speres & it's well cheep).
Having said that, 2nd, just from the pictuers I'd say this actually looks like a very good example of an F50. There doesn't appeare (though remember filler is easy to hide in a picture) to be any rot in the usual F50/20 places. And as it is usually the body work that lets these cars down, I'd be enclined to go look at it, if you've got the time.
