Try not to finish in last place. You still get bonus money if you are in fourth through seventh place.

When you have unlocked the car that has the top speed (305mph) go to the high-jump and as soon as you come OFF the ramp hold B when the green bar gets full let go of B and if you have got it right you will go mega-high

If you go far enough in the High Jump bonus game (hold R at the bottom of the ramp, then release about half a second off the ramp) you will hit the fence wall and get stuck in it. If you wait long enough, the rag doll person will start sliding down the fence.
