European sales of the Mercedes-Benz B class have been on the decline for years. In 2012, Mercedes sold more than 120,000 units of the premium compact minivan. Last year the B class's volume dipped to little more than 62,000. Despite the slump, Mercedes sales boss Britta Seeger says the B class will be replaced. She explained why in an interview with Automotive News Europe Associate Publisher and Editor Luca Ciferri.
