Great ideas everybody.
My list: (many already mentioned)
BMW Individual program
New colors
Full choice of performance options from factory
True LSD as an option (ala audi sport diff.)
Sport/tii model with less options, lighter weight, more power, sportier suspension
NO RFT! (or build a new BMW dealership every 50mi. throughout US)
Fold down rear seats in all cars standard (seriously?)
Most importantly, at least an expanded range of diesel motors for the U.S.!!!!
