From 1977 to 1980, when
British Leyland dropped out of U.S. racing, he won both the
SCCA ProRally series and the North America Rally Championships. In 1981, he competed with an
Audi 80 and
Peugeot 504, but they were not competitive compared to
Rod Millen's factory
Mazda RX-7 rally cars. In addition to his North American schedule, Buffum cherry-picked rallies in Europe, where he became the first and still the only American to win a
European Rally Championship event, taking the 1983 Sachs Rally in West Germany and the 1984
Cyprus Rally, both with Audi Quattro. He also ran the 1969
Monte Carlo Rally in a Porsche 911. Buffum is the only driver in the world to compete in at least one World Rally Championship event in five continuous decades (1960's, 1970's, 1980's, 1990's and 2000). Buffum also helped restart the
Mount Washington Hillclimb Auto Race in 1990 and served as Chief Steward of the hillclimb from 1990 to 2000, again in 2011 and again in 2017. Since the late 1980s, Buffum has owned and managed Libra Racing based in
Colchester, Vermont. He has been responsible for building cars for the Hyundai Factory rally programme in the US and has worked alongside
Vermont SportsCar on their Subaru Factory programme as a consultant. In 2009, he built the first open class Mitsubishi Evolution X, to campaign in the Rally America national series and the Canadian Rally series. In 2014, Buffum was elected to the
Vermont Sports Hall of Fame. ==Complete WRC results==
