Most LC and LJ Toranas have the last four numbers of their VIN scratched into the back of them with a scriber if Adelaide built and probably other Adelaide models as well. But I definetly know this was done on LC, LJ Toranas. Brisbane were written in wax pen most of it dissapears with time. The current consensus is it was done so the ADR TAG went onto the right car when on the production line. I am sure somone could explain it better.
