I was one of the Pit Crew Guys... We had to "change" the tires on the Ford GT. The ad will be great at least it is what it looks like from the storyboard they had there.
The main ideia is that the player enters the pits in the Ford GT and when he stops at the box to change the tires he presses one button inside the car and it "explodes" into parts an reassembles as another car... It chages 3 or 4 times before he gets the one we wants (probably it will be the Opel Speedster [yellow]) and he drives off in high speed leaving the pit crew amazed.
Then we can see some action in the track with almost all the cars including one Pescarolo from the Le Mans.
