It seems that the idiot, Michael Bay, and his obsession with getting profit margings has meant that he will only use the crappy GM cars for Transformers because the fee they pay to have their crap on screen covers a lot of the costs. Whatever happened to putting your neck on the line and going over budget for the sake of art and making the best film possible? Why can't Transformers have Ferraris, Porsches, Volkswagens and the truly great cars? Why must we just see cars that are not internationally recognized? It does defeat the whole feeling of walking down the street and seeing cars that you saw in the latest Transformers movie. Bay is and will always be an imbecile.
