Standing out in the Ford Mustang world is hard. With millions sold over its 50-year history, it seems like everyone and their mother owns one, or has owned one at one point. It’s America’s sports car that exudes styling and performance almost unlike anything else ever offered. Take Mark Sullivan’s custom 1965 fastback Mustang for instance. This two-tone screamer is far from ordinary. With a black-on-orange paint scheme and a slammed appearance, the Mustang turns heads wherever it is.
