Define Gran Turismo 3 Meaning

Gran Turismo 3
I got it in May of 2002. But since it was an unasked-for present, i haven't really played it that much. I'm about 28% complete (but i did use a cheat cartridge to gimme lots 'o' money) and, quite frankly, i will admit this is one game that has truly played me. Has anyone got any cheats that will end my torment?

Gran Turismo 3- I only sit down with it about once every few months and try to complete it, so i'll be about 60 by the time i ever complete it normally. Anyone got any help?
