The set up in QLD is pretty loose, originally it was done for old horrors like T buckets and model A ford, etc, that were in original cond and not modified, that got stretched out and now it is quite "loose" compared to other states, we know it can be abused hence the requirement for incorporated car clubs "dating" officer to approve a car for ergo, the requirement for annual membership in some QLD transport offices is often not asked for, hence some can get away with continual Special Interest ergo plates.
To even try to get State Gov and QLD Tpt to do what we tha car enthusiasts want is nigh on impossible, but if they get a whiff of a possible revenue raiser like charging for issued logbooks they will jump onto it like a flash, I am sure!
Btw I will keep an eye out for a limo h190 a rally guy up here has a couple I can ask him, he posted a for sale on Oscar a couple of months back.
Aegean, please join a car club, just in case a Transport office asks you to prove membership. As Pres of Z club QLD you are welcome, if you don't want to be in the Sydney mob!
