This is the real-life equivalent of a classic GT3/4/5 "One Make Race" - only with really cool cars and requiring really deep pockets.
It would be great if say GT5 would have an FXX, 722GT, MC12XX (is that right?) etc race series.. with the actual cars as they appear in real life (same markings colours etc for each unique car - there are so few afetrall)... allowing mere mortals to play at being a "Billionaire Playboy" for a few minutes
