The BMW 320i and 323i E21, produced from 1975 to 1983, marked a significant turning point in BMW's history. This compact executive car, the first to bear the "3-Series" designation, was a departure from the larger, more luxurious sedans that defined the brand at the time. The E21 was built on a new, lighter platform, boasting a more agile handling and sporty character that resonated with a younger audience. Its sleek, aerodynamic design, with its distinctive shark nose and flowing lines, was a distinctive departure from the boxy sedans of the era and helped establish the 3-Series as a stylish and desirable car. The E21 was initially offered with a range of four-cylinder engines, including the 1.8-liter M10 engine in the 320i and the 2.3-liter M21 engine in the 323i. These engines, paired with a four-speed or five-speed manual gearbox, provided an engaging driving experience, making the E21 a popular choice for both everyday driving and spirited weekend adventures.

The E21's appeal extended beyond its performance and style. It offered a well-appointed interior, with comfortable seats and a driver-oriented cockpit. The car was also praised for its handling and roadholding, thanks to its independent suspension and precise steering. Despite its relatively small size, the E21 also offered a surprising amount of practicality, with ample cargo space in the trunk and a roomy rear seat. The car proved to be a commercial success, achieving high sales figures and solidifying BMW's position as a leading manufacturer of sporty and sophisticated automobiles. Today, the E21 is recognized as a classic and highly sought-after car, particularly in its original condition. Its distinctive styling, engaging performance, and historical significance continue to make it a popular choice for collectors and enthusiasts alike.
