The 1974–1981 BMW 518 Sedan, part of the first-generation E12 5 Series, was a entry-level executive saloon. Powered by a 1.8 L M10 inline-four engine producing 90 PS, it was more pragmatic than sporty (0-62 mph in 14 seconds). Enthusiasts regard the E12 generation as the starting point for the modern 5 Series legacy, appreciating its clean styling and driving dynamics, especially models with a manual gearbox. The 518 is noted for its simplicity and robustness. Today, it is well-suited for classic BMW enthusiasts and collectors seeking a historically significant and reliable cruiser, though its performance is modest by modern standards.
Older BMW 5 Series models, including the 1974-1981 518 Sedan, are prone to oil leaks, cooling system failures, electric window regulator issues, iDrive glitches, and timing chain problems. These common faults can lead to unusual maintenance costs.
