Are there references to past gta games in gta online?

The Wikipedia entry for Grand Theft Auto describes the series as an action‑adventure franchise developed by Rockstar North and published by Rockstar Games, noting its focus on open‑world driving and shooting. It does not provide any information about specific references or Easter eggs that appear in GTA Online. Because the source does not document such references, we cannot confirm that they exist based on the evidence at hand. While GTA Online is part of the same franchise and may include subtle nods to earlier games, the supplied source does not substantiate this claim. Therefore, based on the evidence, there is no documented reference to past GTA games in GTA Online.
