- A 1954 Mercedes used by Juan Manuel Fangio sells for almost $30 million in England
- The auctioneer claims it's the most expensive car ever sold at an auction
- Bonhams says the previous record was about $16 million, paid in 2011 for a Ferrari
The 1954 Mercedes-Benz W196R fetched $29.65 million Friday at the auction in southern England, said Bonhams, with the identity of the buyer not disclosed.
That figure beat the previous record -- a 1957 Ferrari was purchased in 2011 -- by about $13 million, added Bonhams.
"I have handled some of the world's most desirable and important motor cars during a motoring auction career spanning five decades, but I have reached a peak with this legendary grand prix car," Robert Brooks, the Bonhams chairman, said.
"It was a personal privilege to preside over the sale of this vehicle, which is not only one of the most significant motor cars of the 20th century but also the most important historic grand prix racing car ever offered for sale," he added.
Argentina's Fangio used the car en route to winning the second of his five world titles. Soon after it was placed in a museum.
Fangio won a record 45 percent of the grand prix he entered and started nearly 60 percent of his races from pole position -- reigning Formula One king Sebastian Vettel doesn't come close to matching that.
He won the championship with four different teams -- the only man to achieve the feat -- and is also the oldest Formula One champion, claiming the title in 1957 at the age of 46.
"If he were here today Fangio would shake his head and smile his slow smile," Doug Nye, a racing historian, told Bonhams' website
. "He was a humble man, originally a mechanic from a potato town in Argentina and never forgot his roots.
"As a driver he was simply a genius."
