As a European car that's not very suppressing.

American cars = mostly US parts, Japanese = mostly Japanese.

European makers take all sorts of bits from their group of companies and mix and match. Parts from Garrett and other worldwide manufactures (Eaton etc) often end up in European cars because the better (and cheaper) specialist parts are found in the North America.

Ford Europe have Ford, Land Rover, Volvo (also Jaguar & Aston Martin) to chose parts from.

VW have VW, Seat (Spanish), Skoda, (also Maybach & Lamborghini).

BMW started making cars by selling a licensed version of an Austin and did own Land Rover.

That said that I think the diesel engine in the Dodge Caliber over here if from Japan and the Diesel PT Cruiser has a MB diesel.

As to Garret manufacturing in Mexico - is a common trend world wide, make the product where the raw material is, particularly with things like aluminum, by doing it they can add value and make the most of the resource. The Chinese are catching on that making cheap items in China say an aluminum saucepan using manpower, materials and energy, is not in China's long term interest, far better make a more valuable item and get more income.
