I saw a PNG news item last week where the auction was advertised, bids are being received but not yet assessed. The cars are still in the shed at the wharf in Port Morbid.
If that do not have Australian Compliance Plates as I have been told, they are probably destined to a life in PNG thus greatly reduced resale price.
Good luck in getting clean 98 Octane fuel and specialist manufacturers approved service, maintenance and parts.
