This is as fake as Jacko's face.
PD have said repeatedly that GT4 would NOT include any kind of vehicle damage before the game's release, said damage would be a big new thing for GT5.
If any form of damage was in the game, it would common knowledge on these forums about 2 days after the game's release.
Nice try at naivety also: "You can tune the F1?". Hilarious. Good effort, but there is zero hard evidence to support his claims. The pics don't prove a thing. Besides, most of us have crashed the F1 cars many many a time, in every concievable way. There is no damage.
