What items transfer between gta online and story mode?

Grand Theft Auto Online and Grand Theft Auto V story mode operate as distinct game experiences with no item transfer system between them. The Wikipedia entry for GTA Online confirms it is a separate online multiplayer component of GTA V, released independently with its own progression mechanics. In story mode, players control specific protagonists (Michael, Franklin, Trevor) with fixed character progression, while GTA Online allows creation of customizable avatars with separate currency, properties, and vehicle inventories. Rockstar Games has never implemented cross-progression features that would allow money, cars, weapons, or other items earned in one mode to appear in the other, as they maintain separate save files and economy systems to prevent exploitation and balance issues.
