I think I read this article awhile ago (Link no workey), I have never been to China but I frequently read China Car Times and The Truth About cars websites which have quite a lot of coverage on the Chinese market. I would clearly agree with the embracing of Buick by the Chinese (Look at their sales numbers- they're amazing!), I'd say that the "stereotype" for BMW is more akin to that of in the US "Prickmobile," after all they are called stereotypes for a reason. Corruption runs rampant in the Chinese government, doesn't matter if they drive bimmers or audis.
