When i worked at Leavesden Studios we had a Montego Estate to run around in , i disabled it somewhat by throwing hot water onto the windscreen after a particularly cold night ......
to clear the frost, when we were late for breakfast ...
It was very cold driving it around after that , we had to kick the windscreen out of it ... ( it was only ever used on site , to run food to and from sets when we were filming ) , so never went above 10-15 mph unless we took it on the runway for a spin
, but it was terrifying driving it with no windscreen on the runway ....
Shortly after that the drivers side window exploded while i was winding it up, it had jammed and i was trying to 'free' it, that really was the beginning of the end for the poor old beast, it got to the point that you had to wear a pair of water proof trousers and a jacket to drive it, the seats were so wet ....
Happy days ...
