The 1977–1983 BMW 320/6, part of the first-generation E21 3 Series, is a compact sports sedan that succeeded the iconic 02 series. Introduced in 1977, it marked a decisive step in establishing the 3 Series lineage. It is powered by a 2.0L M20 straight-six engine generating 121–122 hp. Enthusiasts value the 320/6 for being the first six-cylinder E21, a model often considered the beginning of the brand's iconic compact sports sedan segment. Today, it is well-suited for classic car collectors, weekend cruising, and participating in classic car shows, offering a blend of period-correct performance and historical significance.
Owning the E21 (1977-1983 BMW 320/6) involves reliability concerns like rapid cylinder head wear, low-quality fuel hoses, and fast-failing fuel pumps and water pumps. Common maintenance includes replacing worn-out bushings, seals, and solving rust issues. Insurance for the E21 can be relatively low, as seen in one example of $446/year for liability only.
