Good question. Only BMW will know the real reasons why the options/packages differ in Europe to the States.
True that the 'Business' (middle) speaker option is cheaper than the 'Professional' version (GBP 545 compared to GBP 815) but then I've also noticed that in the States if you spec the 'Pro' version you get other options included (e.g. CD Changer).
And yep.......we likely drive, here in the UK, with the top down a little (for which read 'a lot') less than you guys.
