On a seperate note, my mum used RAC Windscreens to replace a badly cracked windscreen in her last Corsa.
It was left there for the day to be done, she went to collect it and bought it home. It rained heavy overnight and next morning the the dashboard was wet and the windscreen was leaking. On closer inspection in the daylight the gunk that they use to stick it in had been done in a really shoddy manner and was visable from the passenger side.
The manager got straight on the case and another guy was sent out to the house to sort it. It was replaced again (although rather quickly as the bloke wanted to go home to watch the football
) and luckily never caused any more problems!
