Yea i had Most Wanted but my PS2 scratched, but before that i drove the BMW all the time. But if you talkn about completing the career mode, i have 100% complete theres nothing left for me to do in career mode. the total game is at 97% percent, and challenge series is at 91%. What else can i do?
If you've completed career, you should have your 33 cars, so you should have your reward card, providing that everything else is unlocked.
