Porsche 911 Carrera 4 GTS

The 997.2 Carrera 4 GTS Cabriolet sits at the top of the naturally aspirated 997 open-top hierarchy — Porsche's own performance distillation of the generation, bringing 408bhp from a tuned 3.8-litre flat-six, firmer GTS suspension geometry, widened rear bodywork, and standard centre-lock wheels that immediately set it apart from a Carrera S. All-wheel drive adds genuine year-round versatility without softening the car's intent, and the 7-speed PDK here suits the Cabriolet format well.

This example has covered just 25,816 miles since new in 2012 — under 2,000 miles a year — and presents in an understated Basalt Black over black leather sports seats with a black power hood. The specification is thorough: Sport Chrono with Sport Plus, switchable sports exhaust, PASM adaptive dampers, BOSE audio, heated seats, the Extended Leather Pack, and touchscreen satellite navigation all feature. Factory extras include body-coloured seat backs, Porsche embossed crested headrests, and GTS stainless steel door guards — the kind of detail that points to a car ordered with thought.

The 997.2 GTS Cabriolet in AWD form is increasingly sought after as the last of the air-cooled-lineage, high-revving 3.8s — and low-mileage, well-optioned examples with correct colour combinations are genuinely hard to find.
