Enter „PING” as a code at the cheats screen to unlock all cars in arcade mode.

In career mode, go to your garage and do something with one of your cars (for example,
switch a part or get a different paint job). The game should autosave.
Then, go back to your race menu. Go in a sprint and bet all your money on one car
that looks the fastest. It it does not win at least three races out of four, turn
off the PlayStation 2 and turn it back on. It will load your last autosave.
Try the same sprint again until you win then find a different sprint and start
the entire process again.
