Examples of Friday British cars were legion. Typically, Triumph Stags (British Leyland's "rival" to the Mercedes SLK sports car) must have been made, and designed, on Friday! These examples were all new 'Friday cars': They all overheated, one I had had had the wrong size wheel brace for the wheel nuts, so you couldn't change a wheel, one had the brake warning light wired to the oil pressure gauge and vice versa so when the car ran out of oil(because the gasket leaked ) the wrong warning light lit, one cut out because the crash sensor 'thought' the car had crashed, but started again when the bonnet was slammed, and most had defective ignition...Oh, and this 'drop head' car, had a metal roof, like the Merc's, but it didn't fold away like the Merc's. Two people had to remove and store it in the garage if the driver wanted 'open air' driving !
You young people don't know what real British motoring is!
