A cargo van apparently made by Vapid, whose red oval badge can be made out on the grille, is due to appear in Grand Theft Auto VI. It passes Jason and Lucia's Tulip in the second trailer's closing shot and shows up in official images of Watson Bay and an Ambrosia postcard, and it appears to be based on the 2008-2014 Ford E-Series.
