Background
The Dodge Diplomat is an intermediate car that was produced by Dodge from the 1977 to 1989 model years. Introduced as a higher-priced companion model to the Dodge Aspen as Dodge phased out the long-running Dodge Dart, the Diplomat ultimately replaced the Aspen. Initially offered as a two-door coupe and four-door sedan, the model line also added a five-door station wagon for 1978. From 1982 onward, the model line became offered solely as a four-door sedan.
