Affordable, stylish, and endlessly customizable, the 1966 Mustang Convertible embodied mid-’60s American motoring freedom and quickly became one of the most popular and enduring classics of its era. Following the sensational launch of the Mustang in 1964, the ’66 model year refined the formula with cleaner styling, improved interior appointments, and an unmatched variety of options to suit every buyer. With over a million Mustangs sold in its first two years, the Convertible stood out as the most glamorous body style, embodying the spirit of freedom and fun that made the car a cultural phenomenon.
