Now you can add the extra pictures in comments if you want.

That cop car is a 1979 Chevrolet Caprice.

Definitely a Commodore GS, but I don't think GS/E which I think had alloys instead of Rostyle type wheels.

Hi, glad to be contributing for the first time of many to this page.

A few days ago I stumbled accross this great German big band, the Mardi Gras.bb, and I have since loved their video for 'Psychoflute' (2000), which features prominently (4 stars) what I think is an Opel Commodore, maybe even from the GS/E variant.

There is also some American police car. I would say it's not fake because it has black tape on it as if to render its markings meaningless. 3 stars.
