Can you use gta online money to buy cars in story mode?

Grand Theft Auto Online, the multiplayer component of Grand Theft Auto V, operates with its own in‑game currency that is earned through missions, events, or real‑money purchases. The story mode of GTA V is a distinct single‑player experience that uses its own separate in‑game economy. There is no documented mechanism for transferring money between the online and story modes, nor is there any indication in official sources that online funds can be applied to purchases in the single‑player campaign. Consequently, vehicles in story mode must be bought with the currency earned within that mode, while online purchases are confined to the online marketplace. This separation is typical of Rockstar’s design, keeping the multiplayer economy distinct from the single‑player storyline.
