This may be distressing to some, but I like the way Z4s get dirty. Rather than just getting dirty along the bottom, they get filthy right up the sides, along the bonnet, and on the coupe over the roof and the back end gets well coated. The dirt seems to accentuate the lines of the car, particularly the creases. Often the dirt defines the patterns of airflow over a moving car.
