I worked in a British Leyland car dealership back at the end of the 70’s early 80’s, we had cars roll off the delivery transporter with different colour interior seats, we had one turn up with a door missing, Radio’s were hardly ever in place, just wires hanging out the dashboard where the radio should be. One car had to be rolled off the transporter as it didn’t have an engine, we asked the driver how it got on and he shrugged and said they pushed it on at the yard.
The rubber seals to stop water getting into the car were often missing, wipers were not fitted, paint colours on doors and panels not matching, nothing fitted tight inside - the instrument binnacle rattled something chronic, we had doors, boot lids and bonnets that didn’t close properly.
