Just as a side note question to crv...how many Imperials would you possibly see at car show turn out in Australia...specifically the 72-73 models? 2Dr and 4Dr?
Here in SA we have the All American Day every February (I've been to most of them since 1990 or so), the last couple of years there have been anywhere from 3 to 5 Imperials at the show (300-400 cars, depending on how hot it is), which is OK considering these cars are not well known over here, a lot of 'car' people have never heard of Imperial.
As for the Fuselage models, there's only 1 I know of in SA, the '73 (4-door) I used to own many moons ago, which incidentally, I've not seen at any shows since 2009

, the annual Chrysler Show mainly attracts the Aussie made Valiants and US muscle cars, with the odd big car here and there, rare to see Imperials at this event.
However, there are a few local Imperials that never get shown, but we know of them.
Not sure about the other States, but I'm quite certain that they are a more common sight in places like Victoria, NSW and Queensland.
