The BMW E21 is the first generation of the BMW 3 Series compact executive cars, which were produced from June 1975 to December 1983 and replaced the BMW 02 Series. The series was exclusively built in a two-door sedan body style (except for convertibles made by Baur). Contrary to its predecessor, a 'Touring' body with a sloped rear hatch was no longer offered. Six-cylinder models were made immediately recognizable by quad round headlights, instead of the basic two.
What year is yours; 1975-83 isn't very specific. Which engine does it have? What's the model number of yours; again, 3 series doesn't tell us much.
