I would suspect (since I can't prove it) that there is some level of bias to this or any other report (fanboy, pressure, bribe?, etc) but as a BMW owner, we can compare what have by driving (test, borrow, previously owned) other cars in the segment.
If you can honestly collaborate or dispute what was written about your car, that's what counts.
