As a young man, John DeLorean worked in the engineering department of Pontiac, where he developed the classic muscle car of the 1960s, the GTO. He moved on to become the youngest-ever general manager of Chevrolet and was soon hobnobbing with Hollywood stars. He dumped his first wife to marry Kelly Harmon, a 20-year-old model, only to divorce again and marry jet-setter Christina Ferrare. When DeLorean took to wearing bell-bottoms and had plastic surgery on his face, his new style did not find favor with the bigwigs at General Motors, and he was forced out in 1973. He later blasted GM in a bestselling book, On a Clear Day You Can See General Motors.
