Trump is mad about 'made in Mexico' cars — but this is bigger

Trump takes aim at autos

While President-elect Donald Trump slapped GM and Ford for building cars in Mexico, the biggest automotive import from Mexico ends up not being cars — it's vehicle parts.

Under NAFTA, the automotive industry increasingly became intertwined between the U.S., Canada and Mexico, resulting in an auto parts manufacturing boom south of the border.

The impact of that is clear in U.S. trade data. For instance, in the 10 months ended in October 2016, automotive vehicle and parts imports from Mexico totaled $89.6 billion, dwarfing the next biggest import nations, Canada with $54 billion and Japan, at $44 billion.
