Some ignorant comments without proper justification. For starters, I have read many times that the SA plant has lower defects than the Munich plant. Maybe that's because it has a lower output with a slow moving line but nonetheless it looked like any other BMW plant to me. A BMW is a BMW rather it's built in South Carolina, Germany, or South Africa. All engineered by the same guys in the Fitz building in Munich.
