Prestigious mah 
The GTO is probably the police cars in Australia..cuz the GTO is a
Aussy muscle car..lol..the last pic of the Honda is the Honda
NSX..the best sports car Honda has ever made..it can eat other
supercars and yet is extremely usable on an everyday basis..not
like the Lambos and the Prancing Horses..which is all show, but not
for everyday stuffs..lol Mr. Green
I think another reason is that their highways are dam long and
their country is dam big, and those criminal will do anything to
get away from law. So they are willing to donate Lambos to fish
tail those scums 
Oh yes, thats right NSX, has anyone saw the podcast VODcars? haha
