Oh man, that really sucks. I was looking forward to seeing this classic piece of video game history in photos around the world. Guess the dream is over.
Perhaps we could "generate" a similiar-looking tap? Rolling it in mud, tying it to a string after the car, giving it to the neighbourhood bulldog... Anything's possible, but it will be extremely hard to take away exactly 15% of its condition, so I guess we're pretty much screwed. 85% screwed, to be precise.
