Here in Shanghai I've been discussing the Chinese market with lots of people and no matter how many times you hear them it's impossible not to be overawed by the numbers.

Here's just a few. There's a good chance that there will be ten million cars sold here this year. That means the market's quadrupled in eight years and it will end up being bigger than the US market this year. And it's likely to be the world's biggest market for years to come.

China's doing a good job of propping up GM at the moment too. The US giant's Asian subsidary will sell 1.2 million cars here this year. And that will be two million in five years time at the latest. Volkswagen is having similar success. No wonder everyone's piling into China as quick as they can.
