Your friends in "Hammo racing" whatever that is, speak with forked tongue. My information, and I did not see the car myself, is that there was minimal damage to the car, as would be expected from sliding slowly on to one rock leaving a few specks of red paint.
The "official" shooting of the ad the next evening with the helicopter was by all accounts a dud, especially since the replacement car was black.
Edited to add, Thanks for your input in the following post Woomera. I decided it wasn't worthy of a response.
