The Daimler AG Mercedes Benz logo is seen on the wheel of a vehicle on the production line at the company's international assembly plant in Vance, Alabama, U.S. on Wednesday, May 28, 2014. Mercedes-Benz narrowed the sales gap with larger luxury-auto competitors Bayerische Motoren Werke AG and Audi AG last month as customers sought the company's top-of-the-line S-Class and up-market E-Class sedans.
