if they became readily availble to be purchased and cheap then obviosly their popularity would rise. such as the r33's have.
i remember reading that imports rose from 4k to 12k in one year due to the r33.
now the govt. doesnt like this because these people are not buying aust cars. and then hence what about all the austrialian 's employed by holden, ford, toyota, mitsu etc.
it's a catch 22.
