Porsche Cayman GT4 RS

The Porsche Cayman GT4 RS is currently trading at a median of US$199,000 in the US market, representing a 35 percent premium over its original MSRP of US$147,000. That spread reflects the model's appeal to collectors and the tight supply typical of high-performance Porsches in the used market.

The dataset encompasses only six transactions over the past twelve months, which underscores the thin liquidity characteristic of this segment. With just ten total sales tracked across our monitoring period, individual transactions carry outsized weight in any price movements, making it important to view recent activity as indicative rather than definitive.

Cayman GT4 RS examples show remarkably low mileage at the time of sale, averaging just 1,224 miles across tracked inventory. This pattern suggests that most owners are acquiring these cars as weekend drives or collection pieces rather than daily drivers, a common trait among modern performance Porsches.

The model sits in the stable modern classic tier, a classification that typically applies to cars built within the last fifteen years that have begun to establish collector credentials. With a collectibility score of 5, it occupies middle ground—desirable enough to attract serious buyers but not yet commanding the scarcity premium of rarer variants.

Looking ahead, the base projection holds current valuations flat through both the three and five-year horizon at US$199,000. This neutral outlook reflects the GT4 RS's emerging status: strong fundamentals and air-cooled heritage appeal support price stability, but the thin transaction volume and moderate desirability score limit confidence in upside momentum.
