Publicly? That's not a good sign.

I think Black Audi means nothing these days. I would partially agree with your first sentience if it's 10 years ago and in small city. But today in big cities, definitely no.

I wonder how many people that are not in government specifically buy black Audis in that city to take advantage of this. It's actually possible (although unlikely) that much of the bad behavior is from pretenders.

Thanks for providing some color. I found this article with some more background: http://www.nytimes.com/2012/11/18/fashion/in-china-audi-mean...
