You may have seen my wanted ad for an X5? Anyway one of my girlfriends 'must haves' is a panoramic sunroof. I've been ringing around places today and one guy informed me that I should reconsider one of those as the plastic clips go, the whole 'cartridge' needs replacing costing £3200. He said it is due to the weight of the glass, the under specced retaining clips and that it is a common problem and a case of when not if?
Is this correct? I'm a little sceptical as I had just rung up to ask if the X5 he was selling had a sunroof, it didnt

Any thoughts of opinions?
