One of the interested buyers has asked to see it ahead of the sale and wants to “hear it run,” Mr Osborne said. “And… A high-profile mystery buyer is said to be interested in Ayrton Senna’s Monaco Grand Prix-winning McLaren which is expected to fetch up the £4.5m at auction later this year. “Ayrton Senna was the most charismatic Grand Prix car driver of the modern era,” he added. The buyer was rumoured to be Lewis Hamilton, the 32-year-old four-time world champion who idolised Senna. However, it is understood not to be him. Mark Osborne, head of motorsport at Bonhams, revealed that three people had expressed an interest in the 1993 McLaren-Ford MP4/8, chassis 6, one of whom was very well known.
