Auto's are a type of transmission
Glass's guide is a comprehensive pricing book available to dealers only but manages to slip out on accassion.
What do you call trucks, here they are big heavy tray type vehicles for the transport of goods, F100's etc are utes, short for utility, tray on the back and single or twin cab up front.
4WD's are called trucks by idiots who don't know the difference but for registration (in Vic anyway) are classed as passenger vehicles and cost the same to register ($440.00 for my Landcruiser, same as any car including comprehensive 3rd party insurance which is compulsory).
Pricing varies from State to State.
Not a complete answer to your question but may be of some assistance.
Don't forget that we drive on the right side of the road, not the wrong side :D :D
