Is there a way to get gta online cars in single player?

Grand Theft Auto Online is described as an online multiplayer action‑adventure component of Grand Theft Auto V, distinct from the single‑player experience. The Wikipedia excerpt does not mention any mechanism for moving vehicles acquired in Online into the single‑player world. Since the source only covers the multiplayer aspect and the open‑world design, there is no documented way to use Online cars within single‑player. Therefore, based on the verified information, one cannot obtain GTA Online cars in single‑player.
