Wasn't there (or is there) a troll here that would claim your BMW wasn't a real BMW if it was made in SA? Thanks for the link, I will definitely watch it later.
I took the factory tour when I took European delivery on Dec. 5th in Munich. If you have the opportunity, I recommend it. It's a lot of fun.
FYI on the N55 engine. It's not made in Germany, but Austria.
