The 1966 model altered the trim levels on the Mustang. Also a new grille was introduced, side ornaments, wheel covers and even the gas cap. Automatic transmission became optional on the Hi-Po. New features for the car included a AM/eight track sound system and even one fo the first AM/FM car radios on the market. Round gauges and padded sun visors now became standard on all models.

Differences Between 1965 Ford Mustang and 1966 Ford Mustang
