The Speed Merchants tells the story of Michael Keyser's racing and film experience, across the U.S. and Europe, from 1969 through 1972. He relives what it was like to watch the great Ferrari 512s and Porsche 917s that dominated the world manufacturer's series in 1970; to follow Mark Donohue and Roger Penske as they shook up the Trans-Am through Canada and the United States; to see McLaren's hold on the Can-Am finally ended. The Speed Merchants details the successes and failures of such drivers as Vic Elford, Brian Redman, Jo Siffert, Pedro Rodriguez and Jackie Stewart; and racing at such tracks as Daytona, Sebring, Indianapolis, the Targa Florio, the Nrburgring, Monaco and Le Mans.
