From a Classic Driver online listing:

BMW’s 328 is recognized as one of history’s most important sports cars, and examples are proudly displayed in leading museums such as the Revs Institute and the Simeone Foundation Automotive Museum. The model emerged victorious in its debut race at the Nürburgring in 1936, won its class at the 1938 Mille Miglia and the 1939 Le Mans, and won the Mille Miglia outright in 1940. With over 200 victories, 328s were competitive until well into the 1950s.

This incredible 328 was purchased in 1945 in Germany by decorated fighter pilot and American Air Corps Commander Edward B. Giller, who was stationed there shortly after the war. Retaining its matching-numbers engine, the 328 here has remained in the Giller family for over 75 years and has never undergone a comprehensive restoration. Offered for sale for the first time since 1945, it is a remarkable piece of history that enthusiasts of preservation-class cars will admire and respect.
