Our year 2000 SE alloy wheel centre caps have suffered from broken clips on the backside. In fact the rear ones were 'stuck' in place as all the clips had broken off.
The reason this happens is that they appear to be designed to only 'fit' one way and that is with the small hole on the face of the centre cap (where you insert the tool to pul them off) adjacent to the tyre valve.
Hope that is useful to those who didn't know - another tip is to remove the centre caps before you take your car into a garage so the garage doesn't break them and stick them back in place without telling you
