I'd like to see other cars' statistics before commenting on that.. i find it hard to believe.
Anyway, it could be other things about the car too. How about I drive. Customers have abundant problems using it. Don't forget that Bangle will be designing the new one, so if the problem's with the face, and BMW really agrees with that, the new car wouldn't be done by him again.
Retooling for the 7 series is probably an easier financial decision due to the faster ROI derived from the sales of a car that costs almost? 100K.
