Can i use gta online cars in gta v single player?

Grand Theft Auto Online is the online multiplayer component of Grand Theft Auto V and is treated as a separate game by Rockstar. The official information about its release and gameplay does not mention any mechanism for transferring vehicles or other assets between the online and single‑player modes. Because the online and single‑player experiences are distinct, players cannot import or use cars purchased or modified in GTA Online within the single‑player campaign. If you want a specific vehicle in single‑player, you must acquire it through the single‑player mode or by using the in‑game store in that mode.
