This crew made it all the way across the desert without any major dramas. Here's another photo of the car in some bulldust. It's like talcum powder, and it'll grab your wheels and throw your geometry so far off that it's a fight to stop the car going turtle sometimes.
The same crew (from Porsche Australia) then sent a 996 Turbo up to Cape York the following year. Have done that trip in my Prado and at times the water crossings were more than 600mm deep, I again have to tip my hat to the vehicle and crew.
