You were looking at a car that was not from an auction. Means no auction fees, and the FOB shipping term means you don't need to pay domestic freight either.
Still don't see how you can get rid of the rest of the costs? Perhaps some agents charge lower fees and have access to cheaper shipping?
Regarding Beforward, the shipping terms there are CIF (Under CIF (short for “Cost, Insurance and Freight”), the seller delivers the goods, cleared for export, onboard the vessel at the port of shipment, pays for the transport of the goods to the port of destination, and also obtains and pays for minimum insurance coverage on the goods through their journey to the named).
I.e. they get it to Auckland, and nothing else. You would need to arrange to get it through customs / MPI / Compliance, trucked off the wharf, and the biggie pay GST at 15%.
