Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I'm guessing the Cadillac is coming to Australia? They appear to be building the web site?
Sorry to burst your bubble, lads ... but it looks like cadillacaustralia.com has been registered since 2005. The registrant doesn't seem to be connected to GM or Holden, either. Maybe old mate is (was?) thinking of privately importing Cadillacs at some point?
