In nine years of car ownership in this country, I've never had any of that list done on any of my cars.
Then you have been most fortunate. A cracked windscreen can happen to any car at any point in it's life. Clutches are like brakes and tyres, items with a finite life that will have to be replaced at some stage. A timing belt is a service item, if you did 85k on the original belt in your polo you were living on borrowed time.
