Video: Fangio's Mercedes-Benz could fetch more than £10 million Goodwood could be the venue for a new world record when the Mercedes-Benz driven by Juan Manuel Fangio goes up for auction on Friday, July 12. Lot number 320 in the Bonhams Goodwood Festival of Speed sale could fetch more than £10 million, due to its untouched condition and historic significance. The car won the 1954 German Grand Prix, on its first outing, and continued its winning streak at the subsequent Swiss Grand Prix. Fangio's success in the Mercedes helped him clinch his second world championship title. Bonhams historian Doug Nye describes it as "an extraordinarily iconic piece of living history." The car is expected to sell for a seven, or eight figure sum.
