Arriving locally in 2006 as the Boxster's fixed-roof twin, the Cayman built a following among driving purists and track-day regulars. The 718 generation, including the GTS 4.0 and GT4, was the last petrol version, with production ending in 2025. Resale is strong for a sports car, and the six-cylinder GTS and GT4 models hold their money especially well.
