The Mustang is a sports car made by the Ford Motor Company that was introduced in 1964 and is still being produced as of 2010. The Mustang has been available as a convertible model from the beginning, albeit with a hiatus from 1974 to 1982. Some early models had manual tops that had to be raised or lowered by hand, but most Mustang convertibles came with a power top that could be operated with the flick of a switch. If your Mustang's power top is sluggish or not working, you may have a faulty top motor.
