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
