1st, the driving is pretty nuts; cars go where they please and you just have to avoid them. The road conditions are quite good in Beijing, but poor due to overloaded trucks in the countryside. VWs and Audis are very, very common. Many businessmen are driven in W12 Phaetons, I just saw someone who looked like a German getting into one. My guide told me that the 7 series outsells the 3 series in China. Not very many of either yet though.
