4 inch Crack in Windscreen

[razor]

Has anyone had experience of a large crack appearing at the top corner (driver's side) of their Cerbera's windscreen? I took the car out for a spin on Saturday (putting my foot down here & there), came home, parked it on the drive and found the crack a few hours later. There is no stone chip on or near the crack and the crack is so large that it would have been unmissable when I was in the car. Assuming that there has been no 'foul play', are there any natural explanations? Next question: How much is a new screen? (wince)

Tks for the reply: Not a bad suggestion. Luckily the car's still under warranty, so I'll have a word with the dealer.
