Sebastian Vettel

If Bonhams' estimated sale price of €24,000-€28,000 (US$28,000-$33,000) for Senna's 1981 DAP KART is accurate, it will be one of the cheapest Senna memorabilia items ever sold. Senna drove the kart to fourth at the World Karting Championship in 1981. After winning his first world F1 title, Senna was asked what his greatest regret was. His answer was that he had "never won the World Karting Championship." Senna's kart will go under the hammer in Paris on February 5 at the annual Les Grandes Marques du Monde au Grand Palais.
