It's funny how these sort of attitudes persist. Every 20 years or so a new country enters the market with cars. In the 70s it was "Jap crap," in the 90s it was the Koreans who were denigrated and now it's the Chinese.
Not every marque will be good or successful but there's a heap more innovation happening in China than many of the established countries. It's right to be careful with any brand, it's not so long ago that GM largely left the NZ market, but it's far from an exclusively Chinese issue.
