A Lap of the Globe: Behind the Wheel of a Vintage Mercedes in the World's Longest Auto Race
Phillip Young is the man generally given credit for starting the classic endurance rally concept. In 1997, Young and the Classic Rally Association created the Peking to Paris Motor Challenge. With the approach of the millennium, however, he took on an even more ambitious project?the Around the World in 80 Days Motor Challenge. This memoir recounts the author's adventures while competing in the Challenge from May to July 2000. Beginning with his search for a sponsor and his deliberations in choosing a 1959 Mercedes-Benz 220S, it follows him from his arrival in London through various countries including Italy, Greece, Former Russian Republics, China, Canada, the United States, Morocco, Spain and France. Clemens provides an up-close view of places most westerners never get to see and of the rigors of competition over varying terrain in an old car. Appendices contain information such as the daily route and schedule, the rally results, and a list of the U.S. Mercedes Team sponsors.
