There are only a few of them, and they all have license plates differing by 1 digit only. Not later than a week from when they first appeared every driver in the city knew what to look for
May I point you to the MASSIVE figures every car manufacturer spends every year on R&D? Running a fleet of those cars then is child's play in comparison...
Yes, yes. The Polizia has got a Lambo. But what we actually see on the road are lots of Alfa 156/159s, an incredible amount of Puntos and Stilos and that's it.
But actually those cars look quite sexy with the Polizia and Carabinieri livery
(At least, the Alfas. A Punto is still a Punto, after all).
