Customized cars for maturing market

Thirty-year-old business owner Zhang Yu has long wanted to customize his BMW X5, but he is concerned that unauthorized modifications will make his car fail required safety and emission tests.

With the German auto giant's rapid expansion in China in recent years, a number of BMW owners like Zhang face the dilemma due to the lack of legal guidance in vehicle tuning and modifications.

But the answer could be at hand as AC Schnitzer, a renowned company that customizes BMWs, rolls out an ambitious blueprint for the country.
