Peyote
The Peyote is a two-door muscle car found in Grand Theft Auto IV that looks like a 1955-1957 Ford Thunderbird but the front, with its grille and stacked headlights resembles a 1966 or 1967 Ford Fairlane or Galaxie (with bigger lights and reduced grilles), and the lights on the front bumper might be from 1959 Fords. The headlights could also be from to 1966 or 1967 Pontiacs because they don't point forward (but the grille still looks closer to the Ford's). The Peyote is available in coupe and convertible versions.
It is not one of the more powerful or stable cars in its class. Cops sometimes call it a "jalopy."
