The worst thing about windscreen damage is that there's usually absolutely nothing you can do about it. Unless you make a habit of slipstreaming cement mixing trucks on the highway or challenging a bunch of dirt bikes down your favourite rocky mountain pass, you can't avoid that awful smacking noise happening as a car travelling the other way catapults a stone at you.
If you are lucky, it's a small chip that you can have repaired before it develops into a long arcing crack. Other times, you can see the crack growing before your very eyes!
With my old Merc W123, I had learnt to live with the cracks in my windscreen. The thing is, those initial small cracks gradually seemed to take on a life of their own. Both the driver's and passenger side of the screen all-of-a-sudden had these unsightly cracks that lowered the overall tone of my Merc.
