The youngest four-time world champion set another record, again.

Sebastian Vettel’s helmet sets the world record for the most expensive F1 helmet ever sold at the Bonhams Collectors’ Motor Cars and Automobilia Sale last December 9 2013.

The Red Bull-sponsored helmet by Arai is personally signed by the current world champion and was worn by Vettel at the Nurburgring Grand Prix race weekend this season right when he celebrated his first ever home win.

The helmet generated serious interest not just from attendees at the Bonhams Oxford salesroom and people around the world as bidders jammed the 6 phones lines and the Internet all throughout the bidding process.

When the gavel finally struck, the final price was £72,100 and it went to an overseas buyer.

Proceeds went to spinal cord research charity, Wings for Life.

"These helmets represent the very best of Formula 1 and to be able to offer these items at auction today was exciting for everyone involved.  Not only did we achieve a world record auction price for a helmet but it is made all the more meaningful by the fact the money is going to a very worthy cause,” said Toby Wilson, Head of Automobilia at Bonhams.
