Just to add another dimension to the mix.  Bought a very low mileage almost mint KA and took it to a Ford dealership to get whatever the early mandatory service was, just to tick the boxes (grudgingly).  Got a call from them to say they had broken the front windscreen.  I turned up in person, basically to ask WTF and they said it happened when driving down the ramp in their multi story car park (probably overzealously).  So, it seems this can be a mechanical factor sometimes.  I think I also heard that the Austin All-agro’s windows used to pop out when you jacked it up, but it might be an urban myth.  As for the dealership, they had the front to recommend I call my insurance company to get a replacement.  I was lost for words.  I told them they needed to replace it with like for like, a Saint-Gobain one as from factory.  They dragged their feet so long I had to cave in as I needed the car and I got whatever they fitted, which actually has a strange slightly convex section at the top of the screen.  How you live and learn…

I'm afraid I would have dragged the service manager over the counter!

 

Pity you weren’t there, would have enjoyed watching that : - )  The parts guys at this place are the bees knees and have known me for ages, it just the rest of them.  Suffice to say, they ain’t had my trade for repairs since as I’d rather boil my eyes.

Re the comment about allegro rear windows. I think this was true- many years ago I had an early allegro which I bought for something like £95. It had the original handbook with it. In the handbook was a printed sticker saying that you must not use the rear jacking points (the welded bracket bits to fit the jack into) but to jack in a different specified position instead. That does tie in with rear window popping out storeys

And bizarrely the early allegros had a kind of square shaped steering wheel . I thought it was bent from someone trying to force a krooklok off or something, but it was made like that, unbelievable.

Anyway, back to glass shattering. I recall glass outer door of oven shattering. Oven was on, no one was in the room. The glass exploded all over kitchen.
