I figure you can do those races over and over and have money to buy whatever and I like to just fool around with cars (probably more so than doing the races), so I just did the code so I don't have to do races over and over. I am doing all the races, missions, licenses myself as far as I can go. Eventually if I get to something I just can't do, then the AR max will come out again. Right now I'm around 44% done.
