it is probably a fake...it just caught my eye as the talk was that gillette were to become team sponsors. then i also did hear of sony also..can mclaren make a copy of the mercedes?. the rear of the car looks different though, so I am not sure. i know the nose has to be changed as only the ferrari one from 2014 will be legal in 2015. or the early w05 nose used in Australia.
i will look into it further and try and find the link, the site was all in japanese.
