Canada U.S. content of a new Ford Mustang : 65%

The article is called Parts Paradox: and describes how the big U.S. parts
suppliers are unable to make money on U.S. operations, but do very well with
the overseas units. For example, Delphi wants to keep just 8 of its U.S.
plants and...130 of its overseas plants. Visteon, Fords's Delphi, has 20
U.S. plants and 94 overseas.

On the other hand, foreign parts manufacturers are moving production INTO
the U.S. (dodging tariffs, currency swings, and transportation costs, they
usually locate in non-union regions, sometimes buy struggling U.S. plants
cheap).

Interesting dynamic.
