Toyota are the worlds biggest car manufacturer !!!!
I don't know where you got your figures from but Chery are not the worlds largest car maker and by a long shot . Toyota made more cars than any other company in 2009, Chery are long way down with some 650,000 vehicles.
Toyota overtook GM as the worlds largest car maker a couple years ago with around 9 mil vehicles in 2008. Before that GM was the biggest for the last 70 years!!
In China they produced just over 10 mil in 2009 but that includes all vehicles made in China by all manufacturers, local and foreign.
