Collecting old cars, like a cocaine habit, seems to be one of nature’s ways of telling you you are making too much money. Think of Pink Floyd’s drummer Nick Mason and his private collection of Ferraris. Think of the American pharmaceutical heir Josiah K. Lilly III and his vintage automobiles displayed in an imitation Shaker barn-house at a heritage park on Cape Cod. Or remember Hans and Fritz Schlumpf, Alsatian textile magnates unable to resist another Bugatti. Indeed, the brothers’ passion helped lead their firm into bankruptcy and their collection––more than 500 vehicles, including 150 Bugattis––ended up as France’s national motorcar museum, the Cité de l’Automobile, opened at Mulhouse in 1982.
