The BMW 3 Series E21, launched in 1975, marked the beginning of a legendary lineage for BMW. This first-generation 3 Series, replacing the aging 1800/2002 models, was a compact, sporty sedan that redefined the definition of "driver's car." Built on a new platform, it was smaller, lighter and more agile than its predecessors, offering a thrilling driving experience. Featuring a rear-wheel drive layout and a range of powerful four-cylinder engines, the E21 quickly gained a reputation for its precise handling, responsive performance, and overall driving enjoyment. It was available in various trim levels, from the basic 316 to the high-performance 323i, each catering to a specific set of needs and preferences.

The E21 represented a stark departure from the previous 1800/2002 models, introducing a more modern and angular design language. With its sleek lines, distinctive Hofmeister kink, and flared wheel arches, the E21 established the signature design elements that would define future generations of the 3 Series. It also incorporated several innovative features, including a MacPherson strut front suspension and a semi-trailing arm rear suspension, contributing to its exceptional handling and comfort. The E21's success was not only due to its performance and design but also its practicality and affordability, making it accessible to a wider audience. It quickly became a popular choice for enthusiasts and everyday drivers alike, solidifying its status as a true icon of the automotive world.
