My car is a German import but registered as a uk car, a uk Military soldier, bought the car in Germany and after service brought it back to the uk.
The things i found different about uk cars are :
- Registration did not come up on some online parts stores ( this is now much less as the years go on )
- The exhaust was a one piece front to back stainless system ( a bit of a pain when it went at a weld )
- No front fog lights
- Did have leather heated full electric seats
Speedo was MPH, headlight are uk, I managed to get a full print out from a mate who was a top BMW mechanic of the full build sheet of the car in Germany
I think for a small fee or even free your dealer may be able to provide this for you.
Hope this helps
