One of the greatest mysteries of the world, I think, must be why people are buying luxury goods, including luxury cars. The prices of luxury goods are not determined by any measurable value in the goods. Nor are their quality and performance. The high prices of luxury goods are only due to their brand names. In fact we can always find any other product which has a comparable or even better quality and functions but at a fraction of the prices of luxury goods. The only clue I have is that rich consumers tend to show off their wealth by buying overpriced goods.
