It is my opinion that BMW died at the end of the E38/39/46 life cycles. Remember when they won every comparison? People used to write into C/D and others that they were biased and paid off by BMW!
BMW needs to take a year or two off and find itself again. BMW is not about over-technolized, over weight, detached driving, it needs to rewind 10 years and go off of those chassis and try again.
