Hum, well I managed to break my wife's Polo trim - at the bottom, these clips really do grip and refitting usually means breaking some and even where they are held in the trim, yes, not a pleasant job to need to do. The first time I removed the Polo trim was to replace the hatch handle as it corroded badly (a unique Polo
problem), next time it was to fit a repair kit to the wiper and washer system.
