In swedish stcc/tta, they use a french car, solution-F. Just fit your wished chassis, then race.
Everyone has the same point of stand, the best driver/team winns.
Maybe not interresting for VW, but lots of other teams, like m-sport, prodrive, tmr, bozian, and smaller teams like adapta and weavers would be on it with a small support from a car-manufacturer.
