[Taily]

Holden also called Tailgates, "End Gates" there are a thousand of others. Holden parts book terminology is not something we should aspire to.
I mean who calls a Tailshaft a Propeller Shaft? Or a Dress Rim, Wheel Embellishers?

End gates, comes from the original incarnation of the ute and has it origins at Ford Australia. Side gates and end gates were different lengths and could be removed from the vehicle hence the different name.

Prop shaft? About 2/3 of the world up until front wheel drive started to take on which brought a new term "CV shaft" (not to be confused with CV joint) - and then a new term: Drive shaft (or, more correctly: shaft, driven) started to surface in texts in the 70's and 80's to replace tailshaft as the sexxy "one word fits all" descriptor.

Tongue firmly planted in cheek question for you.... How would you describe the use of the word "hubcap". Is it a big shiny chrome disc or dome shaped thing to cover a wheel rim or a small cup shaped metal device knocked into the outward facing part of a wheel bearing hub?

The real answer to most automotive parts names locally is that we (as a country) have previously bastardised the language a bit and we still continue to.

Some names we don't use but are quite aware of in which countries they belong: fender, wing, hood, trunk, bumper etc fall immediately to mind.
