So it's debatable weather you could use that as it's the interpretation on the wording which as far as I'm concerned fairly open with " model " as the key word to interpret
model") is a particular brand of vehicle sold under a marque by a manufacturer, usually within a range of models, usually of different sizes or capabilities. From an engineering point of view, a particular car model is usually defined and/or constrained by the use of a particular car chassis/bodywork
"Model" is an area open for debate. For Australia, "model" is defined by the document below. Basically, look at the compliance plates on both vehicles. If they have the EXACTLY same model listed, as far as the definition is concerned, they are the same model. I have had this debate with a senior person at Vicroads, he has taken another interpretation of "model", but cannot back it up with any documentation. It was only his personal interpretation. So we have agreed to disagree. My issue was that the Range Rover model (later referred to as a Range Rover Classic) was the same model by the definition and by the manufacturer from 1970 to 1995. Therefore I can put bits from a 1993 range onto a 1976 range. The person at Vicroads disagreed. But they have not wished to enforce their interpretation at this stage. So until proven otherwise, I am sticking with the definition set by the Federal Government.
