Saff, and mk1 Sierra, screens are still available, so it's not a problem if yours get's broken. But if it's your fault you broke it, such as you were trying to remove it yourself, or doing work inside/outside the car and broke it, don't be an honest tit and tell them, just say you don't know how it happened if they ask you
I had a woman with a Pug 307 once, whose screen was leaking. She bought the car second hand, but it was only a few years old, and it was the factory screen that was leaking. She tried Pug who told her she doesn't have a warranty with them - fair enough. She then rang her insurance co, and told them it was leaking. When asked if it was cracked she said no, just leaking. They refused to pay out for a new one on the grounds on "fair wear and tear", so she ended up with a bill of £440 for a new screen through the company I was working for. Ouch!
