I think mine would have to be the wheels (Dare X4), as they don't make them any more (they were made as a special order with fitment for MINI's, a group buy on MINI2 secured around 50 sets a few years back) they are as rare as rocking horse poo. It took me ages to get hold of a set & I really look after them. Was filling up with some go go juice the other week & a white van man asked if they were from an X5, they do look similar though .
