Looks fake to me, as some people in that Audi forum have pointed out. The car might've been in an accident, but those pictures are definitely staged:
#1. The tree would've collasped from a collision of that magnitude. Or at least be bent....
#2. Look around the engine, there's no fluids.
#3. No blood on the seats, or steering wheel where the guy's head probably hit
#4. No tire tracks leading up to the accident
I still dont understand how the accident is "supposed to" happen either. It looks like he skidded out of control, nailed the tree with the side of the car, and thats what split it in half. But that doesnt explain why the front and top is all smashed up.
