Darn GT3....help me out here

hey buddy... you've got to hit "x" when the "circle" is under the car you want... since it moves quick, you've got to time it right... practice on a series that's short... save before the last race, go to the next one, then quit before the countdown to start begins... you'll win the tourney(assuming you had the most points to begin with) then you get your prize and try to pick the car you want...
if you get the wrong one, re-load the game without saving and repeat, thank you, drive thru...
