Easy money:
Enable the "Master Code" then go to the car lot. You will find a red Acura Integra
available for $0. You can sell it for $7,200 and can repeat this as many times as
desired. You can also sell the other cars obtained when that code is enabled.
Enable the "Master code" then go to the career map and enter any event. Exit the
event the first chance you get. After doing this, go into your garage. You will
see that four new cars have been added to your collection: a Nissan 240 SX, a
modern Pontiac GTO, a Chevy Cobalt SS, and a Dodge Viper SRT 10. You can keep
any cars desired, but by selling all four of these newly added cars you can get
$90,290 quickly. You can reset the game and repeat the process until you get the
desired amount of money.
