Just read about some guy in Europe that went to hit the roads in his FXX. Illegal drives, of course... But finally he decided to make his Ferrari road-legal. And you know, he was answered that it is quite possible, and he even doesn't need to rebuild the car, except some minor changes. Though he would pay about 10% of the car's price, i.e. near $250.000...
Don't know who it is and where exactly did it happen, but here's the first FXX "stolen" from Ferrari program. Unless it is someone's bad joke.
