Bob Dylan once said, "The Times They Are A-Changin'." If you lived in Britain in the 1950s and '60s, you'd see custodian helmeted policemen driving around in Morris Minors and Ford Anglias. In the '70s you'd see mustachioed policemen driving around in Ford Consuls and Rover 3500s. Then the '80s rolled around and there were policemen and women cruising around in Rover SD1s and Land Rovers.
