I actually think Ive only got about 8,000 or so, but with that in mind...
I have all the races in sim mode beat except some of the enduros and the final f1 race.
I dont know exactly how many days either, but will probably check it out and come back with an answer.
Problem is that right now Im breaking from the tokyo enduro for a couple of minutes.
It sucks too, because Im not really in the mood to play, but I have got 30 out of 100 laps done, and that would be a nice little waste if I gave up at this point.
I guess it will be a little while before I come back with that info.
