How to do the money glitch.
Go to find cars.
Buy the most expensive car you can
after you click "do you want to buy this for x Cr" and click "yes" you want to either eject disk or hit home button, click start then "quit game"
upon loading the game back up you won't be in the car but you will own it and can sell it. You obtained it for free.
