Marking the pinnacle of Subaru’s GD-chassis era, the Impreza WRX STI S204 was unveiled in 2006 as the ultimate expression of Subaru Tecnica International’s road-going philosophy. Limited to just 600 units worldwide, the S204 distilled lessons from motorsport into a package of precision, rarity, and raw performance.

This particular example is car No.283/600, presented in Crystal Grey Metallic—a hue that highlights the muscular stance and subtle aerodynamic refinements exclusive to the S204, including a carbon-fibre front lip, bespoke 18-inch BBS wheels, and a discreet trunk spoiler. Its presence strikes a balance between aggression and understated sophistication.

Inside, the S204 departs from the conventional STI cabin with Recaro bucket seats trimmed in leather and Alcantara, paired with carbon-fibre accents and a numbered plaque that certifies its exclusivity.

Beneath the bonnet lies Subaru’s 2.0-litre EJ20 flat-four, hand-fettled by STI and enhanced with bespoke internals and a ball-bearing twin-scroll turbocharger, delivering 320 PS and 432 Nm through a close-ratio 6-speed manual and Subaru’s renowned Symmetrical AWD. Tuned suspension with flexible strut bars and specially developed dampers complete the driving experience—making the S204 sharper and more rewarding than any production STI before it.

Offered here in original condition, this S204 represents a rare chance to acquire one of Subaru’s most coveted limited-production models. Revered among collectors and enthusiasts alike, it stands as a landmark in STI’s pursuit of engineering purity.
