How Much Money You Would Have Lost Buying a 2022 Porsche Cayman GT4 RS. £94,000 in 3 Years.

This Is How Much Money You Would Have Lost Buying a 2022 Porsche Cayman GT4 RS.

In 2023, a Porsche Cayman GT4 RS was listed for sale at £219,950. A car with a new list price of £113,700. Someone paid it, or close to it, because that was the market. Allocations for the GT4 RS were trading at up to $150,000 over sticker in the United States. In the UK, over-list markups of £50,000 to £100,000 were commonplace. Dealers held the power. Buyers paid what the moment demanded.

Today, an identical 2022 Porsche Cayman GT4 RS with 13,000 miles is for sale at £125,950.

That is a loss of £94,000 in three years. Before fuel. Before insurance. Before servicing. Before the cost of having £219,950 of capital sitting in a car that was, at the moment of purchase, the most overpriced it would ever be.

What Happened

The Porsche 718 Cayman GT4 RS is a genuinely brilliant car. A 4.0-litre naturally aspirated flat-six engine derived directly from the 911 GT3. 500 horsepower. 0–60 in 3.2 seconds. The most focused, most track-capable Cayman Porsche has ever produced, lighter than the GT3, more communicative, and with a soundtrack that made every journalist who drove it reach for superlatives they usually reserve for far more expensive cars.

It deserved every piece of praise it received. What it did not deserve was £219,950.

The GT4 RS's new list price when it launched was £113,700. The £106,250 premium paid over list in 2023 was not a reflection of the car's mechanical worth. It was a reflection of the allocation frenzy, a moment when Porsche GT cars were so heavily oversubscribed, and dealer waitlists so long, that buyers were competing against each other in a secondary market for allocations rather than cars. In the US, allocation spots were being sold for $75,000 to $150,000 over sticker. In the UK, similar dynamics pushed ask prices to £220,000 and beyond.

That frenzy had a ceiling. Every allocation frenzy does. Once the cars started delivering at scale, once the initial wave of demand was satisfied, once the novelty of being the first person in your local driving road to have one faded, the secondary market normalised. And normalisation, on a car that cost £113,700 new, meant prices falling back toward that anchor point.

The GT4 RS dropped 13.6% in a single year between 2024 and 2025, approximately £30,500 in absolute terms from peak secondary market values. Analysts specifically called it out as the depreciation outlier in the Porsche range: "The Cayman GT4 RS has joined the ranks of the quickest depreciating Porsches. This car, initially hyped to price levels far above MSRP, has seen significant declines. Buyers who entered during the hype are currently facing steep losses."

Steep is an understatement. £94,000 in three years on a car that is mechanically unchanged and still drives exactly as brilliantly as it did when the buyer paid £219,950 for it.

Why the Allocation Premium Is Always the Wrong Price to Pay

The GT4 RS story repeats a pattern that has played out identically across the Porsche GT car market at every previous moment of oversubscription, and it follows the same arc every time.

A highly desirable, limited-supply Porsche GT car launches. Demand exceeds allocation. A secondary market in allocations and over-list cars develops. Prices reach a peak determined not by the car's fundamental value but by the intensity of the hysteria at that specific moment. Then production catches up. The initial buyers sell. New examples arrive on the used market. The price normalises toward the car's actual value, which is anchored to list price, not to the peak frenzy.

The buyer who paid £219,950 in 2023 was not buying a £219,950 car. They were paying £113,700 for the car and £106,250 for the privilege of having it in 2023 rather than waiting until 2024. That privilege has now been fully consumed. The car is three years old and worth £125,950. The £94,000 spent on immediate gratification is gone.

This is what over-list buying looks like when the frenzy passes. Not a gentle drift, a near-£100,000 loss in thirty-six months.

The Opportunity Hidden in the Loss

There is, however, a specific lesson the GT4 RS story offers that cuts both ways.

At £125,950 today, close to its new list price and representing a significant correction from over-list hysteria, the GT4 RS finally makes sense as a purchase. You are now buying the car at close to what it should have cost in the first place. The naturally aspirated flat-six derived from the GT3 engine. The most focused Cayman ever built. A car that has been called one of the greatest driver's cars of the modern era. At a price that reflects reality rather than allocation panic.

The buyer who pays £125,950 today for a car that was £219,950 two years ago is not the victim in this story. The victim is the buyer who paid £219,950 and is now forced to absorb the £94,000 loss to exit.

The lesson, as always, is not which car to buy. It is when to buy it, and critically, what not to pay.
