This first-generation 3 Series, codenamed E21, was a significant departure from its predecessor, the 1800/2000, offering a sportier and more refined driving experience. The E21 was available in a range of body styles, including a 2-door sedan, a 2-door coupé, and a rare 4-door sedan, with the majority being the 2-door sedan.

Available with both gasoline and diesel engines, the E21 offered a variety of performance levels, catering to diverse preferences.

Its sharp styling, featuring a distinctive "shark nose" grille and flowing lines, captured the attention of car enthusiasts worldwide. The E21's interior was characterized by its simplicity and driver-centric design, providing a comfortable and engaging driving environment. While not as luxurious as some contemporary models, the E21 offered a level of craftsmanship and quality that cemented its reputation as a premium compact car. The E21's enduring popularity, even decades after its production ended, is a testament to its innovative engineering, timeless design, and overall driving experience. It remains a coveted classic among BMW enthusiasts and a benchmark for the 3 Series model line that followed. The 3 Series E21 is not only a piece of automotive history but also a reminder of BMW's commitment to creating cars that are both stylish and engaging to drive.
