People buy Leicas for many reasons, one of them being that they are very expensive, but they can afford it so why not? It could be compared to people buying Harley Davison motorcycles, very expensive and, in my personal opinion, only good for making a noise or perhaps pulling a plough, but they like them. Then there is the Rolex buyer, I mean what on earth can a twenty grand Rolex do that a £20 Casio can't, apart from, of course, look expensive. People buy really expensive things sometimes because they don't know what else to do with their money, sometimes it's because they want to show off how much money they have, but often, I surmise, it's because they can.
