Hi, I am a computer illiterate guy, so I don't want to mess up my pc, but also want to play some GTA. How do I insert the mods? Could you guys give me a link such as C:\documentsandsettings\... Im looking to insert the car mods. Thanks Sorry if this has already been asked or showed how to, but I browsed throught out the forum and I did not come up with anything.
