China Top-Selling American Car: Buick Excelle; Popularity: Number one seller

GM sells more Buick Excelles in China each year—a quarter-million of them—than all Buicks combined in the U.S. The Excelle comes in several models, the most popular built by GMDAT (GM Daewoo Auto and Technology, a company GM owns in South Korea). The compact sedan powered by a 1.6-liter four-cylinder is also known as the Daewoo Lacetti and was called the Chevrolet Optra when it sold in Canada until 2008. These days an Excelle runs the equivalent of about $21,000.
