Just make sure you have enough money to buy something at first then change your cash to any number and please remember that "99,999,999" is the max value if you go any higher then nothing will happen for some reason while i was testing it out. When you set the value simply lock it then buy something, The money will now be set and you will now be able to buy anything you want.
EDIT: Make sure your origin is in offline mode before running the game, And on the main menu either press "Go offline" or "Play solo" I personally use the play solo option myself.
Edit2: You can also just win a race after changing and locking your money for it to change.
Edit3: When you end up going "99,999,999" you will then now be able to set it to its normal game value max of "999,999,999"

We turned internet off and ran the game with origin in offline mode.
Maybe that makes a difference, no idea
again, we made the trainer and tested it in offline mode. No idea if the game syncs to some online account.
