KIA Motors is currently going through the perception problem Toyota was going through when they just came to the US. People think they make cheap cars that don’t perform. What people don’t know is that they upped their game by hiring BMW's head engineer and Porsche's lead designer. At the 2014 Pirelli World Challenge, the KIA Optima beat out Porsche, Aston Martin, and the Ford Mustang. No one saw that coming.
