Saw a silver RHD 540iT (Jap import) yesterday. It was not a popular variant given that it was so expensive, but sold a few in Japan, Europe and the US. None were sold in Aus or NZ AFAIK. My 525iT is the best I could find.
And there one was, right in front of my hire 'car'. Being used as a work hack by a painter. Grrr... the world really isn't fair to old BMWs!
