My brother fitted a new clutch to his Austin A105 while on holiday. After towing a very old and heavy caravan. May have been before the days of rescue and recovery.
Worst I've had was a windscreen breaking on the autobahn. Toughened type, so not just a crack. On an Austin 1800. No spare available in Frankfurt or the surrounds, so drove all the way home with a temporary one. Which let in a lot of air. ;-)
