German Automaker Stock Fall After Trump Threatens A 'Border Tax'

German automaker stocks have fallen after President-elect Donald Trump threatened to impose a 'border tax' on cars imported into the US from Mexico. Carmakers in Germany have the biggest manufacturing footprints in Mexico of European automakers. Volkswagen sank billions into building Mexico-based production facilities. BMW made a €1 billion investment in a new plant in San Luis Potosi, producing 150,000 units a year. The US is BMW's largest market, accounting for 20% of the group's annual revenue. Other carmakers will also suffer. Audi of America hopes to produce 150,000 Aud Q5s at its Mexico plant.
