SHANGHAI, China - Cadillac. Made in China.Sounds scary, hey, but that's what could soon be stamped under the bonnet of America's iconic answer to Rolls-Royce. Yep, goldarn it, General Motors will assemble 160 000 Cadillacs a year at a R13-billion plant the construction of which has just started in Shanghai and should be in production within two years. China wants luxury cars and GM wants a fat chunk of the Chinese equivalent of that nation's American Apple Pie.GERMAN COMPETITORSGM chairman and CEO Dan Akerson, pie fork no doubt already raised high, said: "We're going to bring our high-end, premium product here and we're going to see how we run against the competitors from Europe and Japan."The American company aims to capture 10% of China's luxury car market by 2020, GM officials said. Its current total market share in China is around 2.5%.Cui Dongshu, of industry group the China Passenger Car Association, said "There are generous profits in the luxury car market.
