Easy Money Tip
At the options screen select 'Simulation'. After you have gained your racing license and have a reasonably good car, select the 'Racing Calendar' option. Select the 'Single Player' option, beat your opponent, and you will get $400. You will then be asked to either 'Restart' or 'Exit to Menu'. Opt for 'Restart', then just race, win, and repeat as many times as desired to get as much money as you require.
