Need for Speed question
 

I bought a XBox 360 last week and one of the games I bought was Need for Speed Most Wanted. The game rocks, but like anything else I figured it had some cheats and looked online and found a few. One was to unlock the Castrol Ford GT. I did the code, it said it was unlocked to the bonus cars section. Where the hell is the bonus cars section? I've looked all over the place and can't find it!

Ask the person who posted the cheat! Try googling more!
