Mercedes on ceiling

A full size Mercedes car is being nailed to the ceilings in one of Moscow airports . It attracts sights from the people coming through the airport's lobby and always question arises if it's safe to walk right under in - or it might occasionally fall on your head? Well, some say that this is not real Mercedes but is made of plastic instead, but if it so then this should be a very precise copy, because all the smallest details, like brake discs etc are perfectly visible.
