Yeah the Australian cop cars are pretty sweet in general (I'm an aussie expat). That one is a promo car they used in Melbourne. THey would give people "good driving" tickets with little prizes or something

.
In north queensland there are wrx pursuit cars because people were outrunning the cops up there and that was the only thing that could catch them.
EDIT: The ford falcon would be great over here. I don't know why they don't bring it across.
