I went to a site called RS200.org http://www.rs200.org

the guy is an owner/enthusiast and has managed to track down
quite a few of the 200..

and has listed them all, and the known history along with the
Build number and who originally bought them.

its has all the Police car pics, and an e mail from the guy who
was doing the police bit. who said it was just publicity on a Closed road,
and that was the number plate of that 3 dr (so it says)


EDIT: Check out number chassis number 128!!
