Is there a link between gta v missions and gta online vehicle unlocks?

The available source provides details about Grand Theft Auto Online as a multiplayer component of Grand Theft Auto V, but it does not mention any direct link between single‑player missions and vehicle unlocks in the online mode. GTA Online’s vehicle unlock system is described as independent, based on in‑game purchases, progression, and missions specific to the online experience. Therefore, based on the verified evidence, there is no documented connection between GTA V missions and vehicle unlocks in GTA Online.
