Why is BMW not afraid of Trump?

The BMW investment was thought out to export ‘to the rest of the world’, unlike other investment projects focused on supplying the U.S. market. If President Trump imposes a customs fee to vehicles imported from Mexico, BMW might export the cars produced in San Luis Potosi (SLP) to any of the other 44 countries that Mexico has commercial agreements with. 150,000 units of its 3 Series model will be assembled at the SLP plant from 2019 onward. This plant will be one of the five largest facilities of the firm outside of Germany, in addition to those in the U.S., U.K., China and South Africa.
