I did this not once, but twice, many years ago! Specialist bodyshop "welded" the plastic together the first time and it was a lot cheaper than buying another. The S8 is along, large, low slungcar and driving into parking spaces face forward was always the problem as the underside caught and ripped on the reverse out!
Second time it was replaced with a brand new one.........can't remember how much it cost, but it wasn't cheap! Touch wood, not done that for several years now!
