General Motors (NYSE:GM) has lost a fortune in Europe over the past decade-plus: more than $17 billion since 1999. Those losses finally began to narrow in the first quarter, thanks to some painful restructuring -- and thanks to a new hit product, the Opel Mokka SUV.

But there's a catch to the Mokka's success: It's built by GM in South Korea, not in Europe. In this video, Fool contributor John Rosevear looks at why the Mokka's success could be a complicated victory for GM as it continues to wrestle with its German labor union over much-needed cuts.
