The 991.2-generation Carrera 4 GTS Cabriolet represents Porsche's sweet spot between everyday usability and track-focused performance. With just 133 units produced across three model years, this all-wheel-drive convertible is surprisingly rare in the 911 hierarchy. The naturally-aspirated 3.0-liter flat-six delivers 450 horsepower through Porsche's excellent PDK transmission, while the GTS treatment adds wider rear fenders, unique aero elements, and blacked-out details that distinguish it from lesser Carreras. The all-wheel-drive system provides confidence in all conditions without compromising the classic 911 driving experience. As one of the final naturally-aspirated 911s before turbocharging became universal, these GTS models have gained significant collector interest. The Cabriolet's extreme rarity—fewer than 45 units per year—combined with the desirable GTS specification and open-air motoring makes this a compelling modern classic for discerning collectors seeking exclusivity in their 911 stable.
