Easy money
Once the World Class League is unlocked, you will be required to make a profit of $200,000. Go to this event, and spectate Air Trauma. Bet on Crystal; the odds are 20:1. At the very beginning of the race, cheer for Crystal, and she will get a full nitrous bar. Make sure the person in front of her loses their nitrous every time they gain it by booing them. Keep doing this until Crystal has passed everyone including the leader. If she wins the race at the end of 16 laps, you will win six million dollars.
Recommended car
When starting the game and you must choose which car to buy, select the Mazda RX-8 if you want the fastest in stock out of all the other cars. Two other good cars to try at the beginning of the game are the Toyota Corolla GTS and Nissan 200SX.
For League 7 cars, the Infiniti G35, Lexus IS300, and Nissan R32 and R34 are recommended. The Lexus IS300 is good for the Drift Obliterator, Drift King, and Pink Slip races. The Infiniti G35 is good for unlocking performance mods. The Nissan R32 and R34 are good for the circuit and drift racing throughout the game
