The Mustang SVO is a limited-production version of the third generation Ford Mustang sold from 1984 to 1986, with fewer than 10,000 built. Although it departed both physically and mechanically from any prior version of the Mustang, it held the same spot within the lineup, both in terms of performance over "lesser" variants and in prestige, as had variants such as the Shelby-tuned and "BOSS" Mustangs of the 1960s and 1970s.
