the 1980 eagle's appearance differed from the concord's in that the bodies were raised further off their suspension to afford better ground clearance. to fill in the increased visual space between the tires and wheel wells, amc used durable kraton (polymer) plastic wheelarch flares that flowed into rocker panel extensions. the grille was similar to the 1980 concord's, but with the horizontal bars spaced slightly further apart, and the eagle graphic mounted to the driver's side-center. because coupes and sedans carried concord dl equipment as standard, they also carried the concord dl coupe and sedan roof treatments, featuring vinyl coverings, and opera windows. however, bumpers were pulled closer to the body than those seen on concords, due to the eagle having been classified by the united states environmental protection agency (epa) as a light truck, and was therefore exempt from passenger car regulations that required front and rear bumpers that could sustain a impact with no damage. however, as seen on the concord, black plastic end caps were featured on 1980 eagle bumpers.
