I have read the car prize list in this website and I have noticed u can get a nice corvette if u win the American Championship series in Amateur League, but what? After beating all those races, two times, first place in all the tracks i get the same crappy Audi TT , wtf, is this thing supposed to be always like this? Is this possible that I can get the Corvette?
save before the last race. Then enter the race, quit the race and see what you win. If you like it, save the game again and keep it, if you get the damn TT just go load your saved game and repeat. Some people, my self included, press x when the GT3 logo is under the car we want, not sure if it works but superstitions are nice
