The more you import parts, the higher duties you pay and the less you can make the statement of "made in NAFTA".
The majority of your components are German, because your final vehicle assembly point was German. Don't think that a vehicle made in the Mexico will have the majority of it's components/parts built in Germany. Some of the powertrain might be sourced from Europe, but there are also discussions of the German automakers building powertrain plants locally (some joint ventures with other OEM's).
Very true, if a BMW is labeled "made in X country" then chances are the majority of the parts are made in the listed country. If I'm correct the sales sheet even labels the percentage of parts made in the "manufactured" country.
Personally I have faith in BMW and expect them to build great cars. The company is going through some tough changes such as building plants in new countries, diminished engine sizes, and different wheel drives, time will do well but I support their move nonetheless.
