Here in Italy police rarely uses unmarked cars, and when they do, there's no way to tell it is a police vehicle. They have normal license plates, no markings and no permanent lights, since they use magnetic beacons
Usually those car are used by government to escort politicians. They are mostly Alfa Romeo, Audi or Mercedes, and they're always painted midnight blue, hence we call them "auto blu", literally "blue cars"

Not in London, Unmarked cars come are completely random, its not like the US where they will either be Changers, CVPI's, Taurus etc

They're actually unmarked vehicles, you cant tell it from a normal car whatso ever
