The Declasse Yosemite 1500, a two-door pickup classed as off-road that returns from GTA Online's Bottom Dollar Bounties update, is due to appear in Grand Theft Auto VI. Its in-game marketing pitches it as a two-decade-old workhorse, and it has been spotted parked in an official screenshot of the Leonida region.
