I know some things on the cars are different: I have a factory steel sump guard and I think the S African market got them as standard. You wont get that in the UK or US

While BMW messed about with the front top shock mount sizes throughout production on the 525i Euro, ZA stayed with the same ones. If you put the last 7 digits of your VIN in realoem it tells you what market it was built for and the body (HD)type like this:

Just curious I couldnt find anything about the Touring. I am sure you have them dont you?
