BMW M3 E30 Diamantschwarz with 2.5-litre S14 airbox engine

Registered on 17 March 1987, this BMW M3 E30 in Diamantschwarz metallic presents in very well-kept condition, both mechanically and cosmetically, with no deferred maintenance.

During an engine conversion the S14 four-cylinder was enlarged to 2.5 litres and fitted with an airbox, giving roughly 175 kW (238 hp). A BMW M3 E30 Sport Evolution exhaust system with modified tailpipes completes the setup. The odometer was replaced during the conversion at a documented 171,780 km; the current reading of around 15,800 km reflects the distance covered since the engine work, giving a calculated total of approximately 187,600 km. Service history is traceable back to 2004.

The leather interior is close to as-new, the seat mechanisms work faultlessly, and there are no visible signs of wear. Equipment includes:

• M-Technic I leather steering wheel
• On-board computer II, no display faults
• Original Bavaria C radio
• Schnitzer footrest
• BBS cross-spoke wheels, 7.5×16, with new tyres

None of the known E30 body weak points show rust, and there are no dents or notable scratches. The car holds an H-Gutachten (expert report for German historic-vehicle registration) and is TUV-tested until 06/2028.

The M3 E30 marks the beginning of a success story that continues through the M models to this day. Developed as a homologation car for touring car racing, it combines the high-revving S14 engine, low weight and its own widened bodyshell into an undiluted driving experience that keeps it in demand among enthusiasts and collectors.
