Ok well I've been playing a lot lately and now I have 83% complete. I have all the crash newspaper headlines, all but like 2 or 3 signature takedowns, around half of the postcards from special laps, 1 of the 4 trophies, around 115 gold medals the rest being silver or bronze and the last few races I haven't completed yet and like 60 cars as to which I only need one more from crash mode which is the 90 million dollar garbage truck.
Anyways the game is definitly fun. The 100 crash mode missions alone make this game an excellent purchase. I'll probably have the game beat 100% soon hopefully.
