Jim Prideaux's cars: when Prideaux arrives at the border, it is a W123-model Mercedes

These British intelligence chappies are terribly clever, if they can change a car by driving across no-man's land.

I posted a picture of an Alvis, and dear mr. Daviddb remembered that Prideaux drove an Alvis. I search a bit in the files and I could make these pictures.

In case anybody is wondering, these are scenes from the television series Tinker, Tailor, Soldier, Spy.
