True, but why? It must be rarity, and attracting people who want one as an investment; as rockits' experience reflects, it's not that much better as a car to drive.
I suppose it's a bit like the difference between a Rolex and a (Rolex) Tudor; they both tell the time perfectly well (as does a £20 Casio, but I digress...), but one costs a lot more than the other.
