Have just bought and am really impressed but need some advice. I currently play Arcade on novice and have attained about 20,000 kudos, ranking 4 and about 7 tokens. I know this is basic but i'm confused as when i get a new ranking and tokens it asks me if i wish to keep them or use them but cannot work out how to use!!! Screen only says A to continue or B for back - how do i use the tokens??? Also when i do unlock cars will this allow me to choose different cars for races rather than the fixed cars given?? An idiots guide would be appreciated!
