higher end stuff always does seem to be more tightly controlled.
Here is a story that I've heard - no idea if it is true or not - about Ferrari. Supposedly, they take pre-orders and total them all up. Say they have 1,000 people who put a deposit down and want to buy a new Ferrari next year. Then Ferrari only makes 999 new Ferraris and 1 poor bastard gets his deposit back. This way, they ensure that demand is never fully met by the supply they offer, and this keeps the retail & secondary prices high.
Interesting concept. Again, I have no idea if it's true though.
