Easy money
On your third mission where Ray asks you to collect $1,500 and deliver the money to his Auto Shop in La Guardia, enter the La Guardia Circuit Race. Win first place under any difficulty setting. Upon completion of the race, the Circuit will close and you will not be able to race again. Save the game (provided that the autosave feature is turned off) and restart the mission. The La Guardia Circuit Race will then be re-opened, but you will retain the money you won from the last race. Repeat this to continue earning as much money as desired. Once you have the money you need, return to Ray's Auto Shop and to the green marker to make upgrades to your cars. This makes it easier to win the La Guardia Races. To complete the mission and continue the game, have at least $1,500 and go to the yellow marker at Ray's Auto Shop at the start of the mission.
