I think they are going to rob a bank. People on one side of the street will tell the police it was a black Audi, people on the other side of the street will say it was a white one. The police will think the eye witnesses are off their meds.
While I do not think I would ever do 2 colors on the body of my car, I do run silver wheel on one side of my car and gun metal on the other because I couldn't decide which one I would like better. Sounds odd but you do only see one side at a time and its a little more inconspicuous than half the car white and half the car black.
