i am no import knowledgable person, but i have heard it is much more difficult to import cars into this country.
something about importing only pre 1989 minis (they are less reliable, and pretty much like the old ones found here)
you may like to read up on this website
www.ozcooper.com.au
by the time you have paid everything off and gone through all the checks
it could be a very exxy but average mini.
if youd like to import a mini for its newness (rover fuel injected 90's)
then there are a fair few you can buy in aus.
