What vehicles are transferable between gta story mode and online?

GTA V story mode and GTA Online are fundamentally separate game modes with different save file systems. Story mode uses a single-player save file that tracks vehicles owned by the three protagonist characters, while Online uses a separate character-based progression system. There is no built-in mechanic that allows vehicles purchased or stored in story mode to appear in Online, nor vice versa. Any perceived 'transfer' typically involves players using external services like the Rockstar Games Social Club to purchase the same vehicle model in Online using in-game currency, but this is not an actual transfer of the specific vehicle instance between modes. The two modes maintain independent garages, properties, and vehicle ownership systems.
