Thanks for the info. I got it figured out. I should have listened to my gut instinct than to listen to any sales staff whether in China or the US. Anyways lesson learned, good thing i've only been driving around for a week while being misinformed.
The pollution here is pretty bad, but it's a lot better than it was a few years ago. The Chinese government has taken initiative to force high polluters(industries) out of the big cities. They in turn pollute in less regulated suburbs or other countries (vietnam, laos, eastern europe, etc)
Sorry to hear about the dirty planes, i don't know what can be causing that. High humidity + pollution? Maybe planes from highly polluted areas in Florida have the same problems? Just my guess
