Are there any unlockable items from gta online in gta story mode?

Grand Theft Auto Online functions as a standalone multiplayer component of GTA V with its own distinct progression system. The evidence confirms that Online is designed as a separate game mode allowing up to 30 players to explore the same San Andreas map, but it does not indicate any mechanism for transferring items, vehicles, or unlocks between Online and the single-player story mode. Each mode maintains independent save files and progression, meaning purchases made in Online (such as vehicles, weapons, or properties) do not carry over to story mode, and vice versa. Rockstar Games has consistently treated these as parallel but disconnected experiences within the broader GTA V ecosystem.
