  1. To my eye, despite the twaddle about a stick in water, the car looks like it is simply unresolved. The front is frumpy and sad, although thankfully less “SUV-like” than the 5 and 7-series, the side is pleasant and the rear is an after thought.

    The previous model had presence, it was masculine and was confident. This car looks diffident and inert.
