Just an observation... when I think of Police cruiser, I don't think of some black & white painted Bug Veyron, or a SMART car in police livery.
I think INTIMIDATION. I want to believe that when the heat shows up the bad guys are apt to split . I want the very appearance to that grille in the rear view mirror to subjugate that twenty-something, hormone saturated, motorhead to think twice about passing on the shoulder. I want to know that the LEO has ALL the kit s/he needs to deal with everything from fully immolated 18-wheeler to a preggo ready to pop. It isn't any of these machines....
Of course, it's all relevant to age.
When I was 17 it was one of these.
