What are the completion bonuses for gta v story mode?

The verified evidence provided discusses Grand Theft Auto: San Andreas, which is a 2004 action-adventure game developed by Rockstar North and published by Rockstar Games. This game is the fifth main installment in the Grand Theft Auto series and is set in the fictional state of San Andreas in 1992. The evidence describes the game's open-world design, third-person perspective, and narrative following Carl 'CJ' Johnson's return to his hometown after his mother's murder. However, there is no information provided about completion bonuses for Grand Theft Auto V's story mode. Since the evidence specifically pertains to San Andreas rather than GTA V, I cannot provide details about GTA V's completion bonuses based on this information.
