Today Bay stated the Ferrari is a 'Con in the movie, despite most, if not all of his on-set pictures spotted to be with the Autobots. People have created a rumor mill of sorts in saying that he's a 'Con spying on the Bots or the other way around, due to the famous "Anti-Spoiler Campaigns" run by Bay. If if he's a Bot, could it be possible that he's Mirage, as some people had rumored before we knew this information? I mean, in the G1 Cartoon, he always was sort of the spy of the group, turning invisible to sneak up on the Decepticons.... Maybe it's sort of replicated in DOTM. I'm probably wrong though, but give your own input!
