these guys are just completing their CYMC (Cape York Misers Challenge) and have been doing regular updates on the trip report. basically they all had to buy a cheap fourby and try and get it to the cape and back, original target was $3K for vehicle and fuel, but it's not a figure set in stone.
cheers.
