Yeah, the taxes on importing luxury / exotic cars to Oz is ridiculous (but probably keeps a few jobs here).
When my brother was living in Chelsea, in London his street was full Ferrari's, Porsches and Audi R8's just sitting on the street in front of the apartments. Was thinking that I'd make sure I could at least park it in a garage if I bought one.
It was bizarre though, as here you are lucky to see a few in your life-time (being in the country) and yet they were so common and unprotected over there.
