It was then sold to a mechanic who repaired it, thus removing the defective supercharger. In 1945, a wealthy american doctor who had just arrived in England bought the car and a year later, he brought it to the US and sold it to Bugatti enthusiast Mike Oliver. In the hands of that owner, No. 57374 received the US regulations changes and was painted a dark red. In 1953, Oliver decided that the car should have the "C" specification refitted. As a result, No. 57374 was brought back to France at the Bugatti workshop to make this change and, once completed, was returned to the US.
