Auctioneers Bonhams said the Austin Healey 100 Special, in "barn find" condition, was sold for a world record price of £843 000 (Rs 38.4 million) at auction in Weybridge, England.
Driven by Lance Macklin at the Le Mans 24 Hours sports car race, it was rammed from behind by Pierre Levegh's Mercedes which then flew into the crowd and killed at least 83 spectators in motor racing's most horrific crash.
The car was impounded by the French authorities for 18 months before being handed back to the Donald Healey Motor Company for repairs, racing through the late 1950's and into the 1960's.
Bonhams said it had been stored, untouched, by the vendor since he bought it in 1969.
