For all who responded to my tail of woe, here is the update...
After making arrangements on Saturday, today Monday) some nice people from a firm called Autoglass took my nice red Corrado away and returned it 3 hours later with a brand new sparkling windscreen
Yippee - I can now drive safely when the sun is low in the sky!!! The only problem now is that the rest of the bodywork is looking distinctly shabby in comparison
Btw - I now know why I have insurance (apart from the fact it's compulsory!). The cost of a replacement windscreen works out at about $650. All I paid was the excess (about $80 in your funny transatlantic currency)
Mouse is once again a happy stress-free rodent
