few changes were seen for 1983. the series 50 eagle kammback and series 30 eagle 2-door sedans were both dropped from the line, due to slow sales. the series 30 eagle sedan lost its limited trim line, leaving only the base model in the eagle sedan line. the series 50 sx/4 and series 30 wagon continued basically unchanged. all were measures to save production costs by pruning the slow-selling models from the line, thereby streamlining their processes by reducing production variations, and therefore, complexity.
