Well since they have stopped buying gold (if you believe those figures, then you will believe anything) they need to buy something else. I am not sure I greatly care if unused cars here become unused cars somewhere else. My hobby is gluing then together and attempting to drive them. Up to a point it does not matter what the car is. Most Classic Car prices are beyond an amount I wish to afford already, so I am out of that market. There are better things to do than tie your money into too many cars now.
Is the real reason for this that the Chinese have seen the general rise in Classic Car prices and want a slice of the action. However Classic Cars is a bubble investment based on economies offering very few other good freemarket investments. So if they come in and buy up all the already overpriced cars, then, later, the bubble pops, I see that as a positive for our nation. One of few. As an owner of too many cars, bring it on, I say. For those who really use the cars will continue to do so.
Asia was already a prime buyer of Classic Cars anyway. I have sold more cars to them in 20 years, than anywhere else. It tends to be done quietly, and not least as the wealthy over there are very wealthy. It does not always suit them to advertise that they are buying. So you just do not get to hear about it. My suspicion is the first two biggest microcar collections are Asian. China is just catching up, as it is not a free market economy.
