Two MAJOR bloopers

Okay so I'm watching the movie and come to the part where the garage girl is explaining to the german chick about her new blue 350z and so she says that the tires are NOT designed for drifting but later on the pizza guy and the german chick are doing doughnuts..i mean seriously wtf AND during the same garage scene the doors slide upward to open in a traditional lamborghini style but then when the german chick is going with the pizza guy, the doors open like normal ones!
