Publicity photo. There was never a genuine RS200 police car. It was a mock-up just to announce that "it doesn't matter if you have a Sierra Cosworth (one of the fastest cars at the time) as we will always have something faster to catch you"

Some great pics above.
Here's what pulled up outside my house last yr. One of the drivers is an original EscCos police driver: I recognised him from the 'special' tv program with the EscCos.
