520/6 Sedan (1977-1981)

Can you afford a 1977-1981 BMW 5 Series 520/6 Sedan in 2025?

The 1977-1981 BMW 520/6 Sedan, part of the E12 generation, is described as a pleasant car to drive with crisp, well-aged styling. Enthusiasts find that its handling is fun but often has excessive understeer. It is infamous for its problematic Solex 4A1 four-barrel carburetor, fuel consumption, and cracked cylinder heads, as well as a general lack of corrosion resistance, meaning few survivors exist. Powered by a 2.0 L M20B20 straight-6 engine delivering 122 hp, the 520/6 is now best suited for a classic car collector seeking a characterful, smooth engine for leisurely cruises, rather than daily driving due to maintenance concerns.

Operating expenses for the 1977-1981 BMW 520/6 Sedan are uniquely affected by its heavy fuel consumption. Reliability concerns include issues with the Solex carburetor and potential cracked cylinder heads, leading to unusual maintenance costs for these specific repairs.
