In 1974, Mark Donohue took a year off from driving at the height of his racing career to write "The Unfair Advantage," a candid and revealing book about his journey through the world of auto racing -- from amateur SCCA races in his own '57 Corvette to winning the Indy 500 in Roger Penske's McLaren M16. This new edition contains over 60 additional photographs and comments from people who worked and raced with Donohue during the 1960s and early 1970s.
