Rare Bugatti 57S Atalante

A rare Bugatti supercar left to gather dust in an English garage for half a century could fetch millions when it goes under the hammer next month, a report said Thursday.

Experts believe the car -- one of just a handful ever made -- could fetch as much as six million pounds (6.2 million euros, 8.7 million dollars) when it is auctioned at the Retromobile car show and sale being organised by Bonhams in Paris in February.

Harold Carr, a surgeon, apparently abandoned the rare Bugatti in his lock-up in northeastern Newcastle after buying it in the 1950s.
