This brings up another thing I don't understand about the way cars work in other countries... registartion.

Why is it, that used cars in Australia (and maybe elsewhere I guess) list as a selling point the "rego" (registration)? When the new buyer buys the car, it will have to get a new registration, plate, and deed anyway won't it? That's how it works in the US... I guess maybe this means that unlike here, the registration is not bound to the owner and the car, but just the car itself? (For example, three different people can own the same car over the course of a few years and still have the same rego/plate?)
