Actually if you look at the window stickers they will give you a % of parts that come from the mother country.

For example a Honda S2000 uses 100% Japanese parts, an Accord uses about 17%.

I think MB's run in the 50%-70% range.

If I remember correctly a CL55 AMG uses 57% German parts.

MB has been cranking cars out of South Africa for a very long time.
