Created to homologate BMW's touring car race campaign in the mid 1980s, the classic E30 remains the enthusiasts choice as the purest of the M3 line.
The M3 could easily be distinguished from the standard E30 thanks to an aerodynamic body kit, but most of the real changes took place under the skin. The 2.3 litre, 4 cylinder engine revved all the way to 7300rpm, initially producing around 200hp. The E30 was revised with further weightsaving and a small power increase to 220hp, known as the 'Evolution 1' model, followed by a similarly enhanced 'Evolution 2'. A final 'Sport Evolution' model arrived in the early 1990s, with adjustable aerodynamics and an enlarged 2.5 litre powerplant.
At around £23k when new, the M3 was quite expensive for the time, but nothing compared to asking prices today - up to £150k for a pristine Sport Evo!
