I had a Morris 850 Mini quite a few years ago that failed because the wipers did not self park - even though they were working as designed and in 1962, mini wipers just stopped where they were when you turned off the switch. It took a bit of talking, but on my second inspection, I convinced the workshop owner (one of his mechanics had done the original inspection) that it was ok because it was working as designed. If I needed to change to self parking wipers, that would have meant putting a later model wiper motor in the car - not that difficult to do and certainly easier than on an Escort, but I was a lot poorer then

and I was trying to get the car on the road as cheaply as possible.
