The car on the picture actually is a car of the former City of New York Police, which is a different department than the New York New Jersey Port Authority Police...
In the meantime I found out that the older NYNJ PAPD cars were yellow with blue sides, then yellow with a blue band on the sides and finally the current Color scheme: white with a blue band.
Dit is een Greenlight Ford Explorer, met de bekende decals van BilBozo (te verkrijgen via
