The 718 Cayman GT4 RS takes the GT4's 4.0L flat-six — the same block as the 911 GT3 RS — and extracts 493 hp with a 9,000 rpm redline and intake trumpets routed through the rear windows. PDK only, sold in limited allocation, and priced accordingly on the secondary market.
Used GT4 RS listings frequently exceed original MSRP; condition, mileage, and documentation drive the spread. FlatSixFinder's deal scores use real BaT and PCarMarket closed-sale data to identify the rare examples priced at or below genuine market value.
