1. Testosterando - is good to finish all races, just upgrade it and that's it, don't spend your money until the end. Your money goal is 1000000, and with race #36 you can acheieve that easily - then go spend the money on everything

2. MISSABLE - when you are asked to do a side mission, always accept and if you think you will not make it, restart the race mid game! If you fail the mission and continue after the race, it will not show up again.

3. If you're driving a normal race (no mission), if you are not winning, don't restart, just finish the race, because your fuel goal is 10000. After you win the last car (Penetrator 8086), if you still have to spend some fuel: drive the #36 with that car (has 0 cost on repair) and keep crashing to the palm trees all race, get it wrecked - refuel, repair, continue race - do it again!
