This is an actual BBC documentary from 1993, and it's sort of dull as fuck. But at the same time it's super-fascinating to see these travelling reps base their entire notion of success or failure on a cast-iron hierarchy of saloon car trim levels.
Highlights include the guy who cried when his Cavalier got swapped for a Maestro Clubman, the maverick in a Fiesta XR2i and the chap who checks for headlight washers in his rear-view mirror before letting other cars overtake him on the motorway.
There's no way this wasn't an inspiration for The Office. Check it out.
