Does Australia have a big enough hobby market to support a local model company producing injection-molded car kits? Like a version of Moebius or Galaxie International, and kits of Holdens and Oz market Fords/Chryslers?
Perhaps Aoshima's Australian distributor could have a word with them. I hear he posts on here.
Seriously, if there was a chance of anyone making $$$ producing kits of these don't you think they'd be doing so? The local market is too small and while there are a few enlightened overseas viewers of the races I doubt there are enough who would buy model kits you have to put effort into (and have some skill to build) when they can buy a die cast
