This particular Sport Evolution presents in exceptional, collector-grade condition, preserving its original factory panels, original VIN tags, and period-correct finishes throughout. The interior remains remarkably crisp, with the high-wear suede contact points displaying light, honest patina consistent with careful ownership. Mechanically sorted, the engine revs freely to its 7,250 RPM redline, paired with precise shifter engagement and tight chassis dynamics. This E30 was imported to the US after 15 years in Japan, and benefited from diligent servicing on arrival. Complete with its original owner’s manuals, stamped service booklet, and a comprehensive binder documenting its history and maintenance, this Evo III stands ready for either premier concours display or spirited backroad evaluation.
