There’s nothing more 70s than a car with a vinyl roof, and I still think a car with a reconditioned one looks rather swish. But most survivors from the 70s now look like the one in the cartoon.

The car is a British Leyland Princess – a Ford Cortina competitor that could have been a world beater if only they built them well enough to hold together for longer than one week. And if the management had given it the hatchback it was so obviously designed for.
