Porsche's Sonderwunsch program hand-built two exclusive 1-of-1 versions of the Cayman GT4 RS.

The Sonderwunsch models feature exposed carbon fiber on the hood, roof, doors, and rear wing.

Subtle gold accents on badges and wheels provide an upscale contrast against the grey and carbon.

Inside, gold stitching and seatbelts complement red leather with custom "Sonderwunsch" lettering.

They retain the GT4 RS's brilliant 493 hp 4.0L flat-six for ripping track times.

Numbered badging denotes their special status among 1 of just 1,000 Cayman GT4 RS models.

Only Porsche's ultra-exclusive Sonderwunsch program could create such unique supercars.
