Mercedes Benz is celebrating its 130th birthday. Automotive museums around the world are showing the long history of the automobile.Mathis Kurrat takes us on a tour of the Shanghai Auto Museum in Shanghai, which has one of the legendary 130-year-old Benz cars. Mathis wonders where the Chinese cars might be. Wherever he looks he sees European and Ameican vehicles from every decade. Big "riverboats" from the US, little sports convertibles from Britain, and even cars made in China's arch-rival, Japan. Finally he finds cars designed and built in China, like the Shanghai SH 7221.
