The 1967 Mustang received significant styling changes that included revised grille and taillights-the taillights you recognize on Mustangs these days with the three vertical lights on either side of the tail.
The 1971 Monte Carlo noticed only slight styling changes and an added stand-up hood ornament. The SS got new "European symbol knobs" and a four-spoke steering wheel became optional.
The 1970 Charger was changed yet again and gone was the split grille that was introduced the previous year. New front fenders and a new lower-priced version with bench seats and a more modest trim package were added to the mix.
