This '57 Maserati 300S was raced 4 times in 1957 by Fangio, who scored 4 first place finishes with it before his team manager sold it for a fantastic profit to a wealthy Brazilian playboy who had no interest in racing the car. He only wanted to flip it after Fangio officially retired from racing, for a ridiculous profit
