At the time of production, Bugatti could not find a buyer, and during the Second World War the Bugatti family immured the car in the wall of a private house of theirs, so it will not to be found and confiscated by the Nazis. In 1950 it was bought by the famous American racer Briggs Cunningham - for the equivalent of $3,000. Up until 1986 the car was in his own personal museum. After the museum closed (for financial reasons), Cunningham put the car up for auction at Christie's, where it sold for $9.8 million.

The buyer, Swedish "Real Estate King" Hans Thulin, went broke just three years after the purchase. In 1990, he sold the car, reportedly for $15.7 million, to the Japanese conglomerate Meitec Corporation, which owned it for the next ten years. It is known that in 2001 that the car was sold, and again the price is suspected to be around £10 million.
