In the beginning of the movie, where Kip steals the porshe, he breaks one of the glass doors. When they go to drive back out, both doors are there. And it's the same set of doors, because the car that they drove there in is on the side where they drive out.
This is not true...
Kip smashes the doors with the Porsche logo on, after breaking into the car, they then drive through some other windows to get out...
When they smash through the windows, in the Porsche, they are heading straight for the car they arrived in, but if you look at when they arrive at the Porsche garage, they walk away from to the car, towards the Porsche logo doors..
