One of the many things that makes the story of Ford vs. Ferrari at Le Mans in the 1960s so compelling is that for most of the protagonists it was personal. Henry Ford II felt that Enzo Ferrari jerked him around after offering to sell the Ferrari company to Ford. Enzo still bore a grudge for his factory getting bombed by American forces during World War II and badly wanted to beat the American upstarts. Ken Miles was an aging driver, respected by his peers but outside of the limelight. Beating Ferrari—the man as much as the team—was likely most personal to Carroll Shelby.
