One of the defects I noted during my pre-purchase inspection was damage to the nearside side skirt, probably caused by manoeuvring near a high kerb. This impact removed some of the fastenings for the side skirt and the jacking block. It also caused some damage to the seam between sill and floor but nothing to cause concern. The damage was noted on the past two MOT inspections as an advisory only.
I ordered a new genuine BMW jacking block on ebay and it was fitted today.
