Thing is, I have:-S And I've checked with VicRoads and the Police, and as far as they know, it isn't classified as a high powered vehicle YET, and if a vehicle was purchased before new definitions come out, then, as I'm told, you wouldn't be bound by the new definitions.
Its the last part I want to clarify because VicRoads doesn't want to put anything in writing, i.e a statement, only verbal confirmation.
