In 1977, the oul man bought an ex-Met unmarked car, a 1973 Cortina 1600 L Decor "TMC 371M". The seller was a serving Detective Inspector who in turn had bought it from the Met.
There were a few mysterious holes in the dash, plus a series of switches hidden beside the steering column. We never did find out what they were originally used for.
It had been quite well cared-for during its police service.
The black vinyl seats were lethal in summer. I remember the oul man replacing the nearside wing once due to rot.
By 1985 it had developed a severe reluctance to start in cold weather, so it was flogged off to a Spanish restaurant owner for £150. Since then, all of the oul fella's cars have been German.
