The Riata Classic is a Vapid vehicle due to appear in Grand Theft Auto VI, known so far only from a debug menu in the September 2022 leaks, where it was tied to an unnamed vehicle-theft side mission given by a character called Wyman. It has not been seen in footage, but its name suggests inspiration from an older-generation Ford Bronco, given that the standard Riata appears to be modeled on a Bronco rendering.
