While we doubt any sane private buyer would care about owning a small Hyundai decked out with 'grass' bodywork and interior, a giant football and goal posts, we guess that a car dealer or a sports shop could use the car as an attention grabber for their store.
In any case, one of Hyundai's two i10 2010 World Cup promotional cars has been put up for sale on eBay with all proceeds to benefit "BEN", an automotive industry charity in the UK for those who work, or have worked, in the automotive and related industries, as well as their dependents.
