I havnt really bothered with the challenge sheets so far but I need to get a triple payback to complete a challenge sheet to get the cool nixon racing car, but what exactly is a triple payback??? is it to blow 3 cars up with one crashbreaker? or is it to let a rival smash you then get revenge on him 3 times?? Ive searched for this and found a good gamerpoint challenge guide but cant find the answer .
thanks
