"Anyhoooo, the point I'm clumsily making is that in say a year, when everyone is either SIDS compliant or their plane is sitting in a kindy playground, Australian Cessnas will be, worth the same as against each other."
Rubbish SID's aint SID's and AUD($) likes low time imports not local sitters. But then remember it only Cessna and most places repeat all SID,s each 10 years in Australia. (that is minimal $1,000 per year EXTRA in labour).
