The other thing worth mentioning is that like the "black cab" in London and the Ford Crown Victoria in America, there appears to be a car that seems typical to Chinese taxis. The suburban ones are always Citroen AXs. The Regional cars are always Volkswagen Jettas.
The funny thing is that both cars are very old models. The Jetta model can't have been made in Europe for 20 years, while the AX isn't much younger. I don't know why they do that. Do Citroen or really think that they can pass off 20 year old crud off as new here?
