About the BMW E12 (1972–1981)

The BMW E12 was the original 5 Series, launched as a replacement for the “Neue Klasse” sedans. Known for its sharp design by Paul Bracq and strong inline-4 and inline-6 engines, the E12 set new standards in handling and comfort. Models included the 518, 520, 525, 528, and the rare high-performance M535i, considered a spiritual predecessor to the M5. The E12 is now a respected classic, known for its solid mechanicals, clean styling, and growing collector appeal.
