George calls his '56 Vicky "Incognito" because it's disguised with Roush Mustang parts. Roush suspension components were grafted to the stock frame, a Roush supercharged Mustang GT engine provides power, and the Roush Mustang interior was modified to fit the '56. Early '60s custom elements include '55 Olds headlights, '56 Merc taillights, and '55-'56 Mercury door trim.
