SA→UK arbitrage in pre-1990 Porsche 911s: the FX has eaten the spread.

Twelve months ago, a tidy 1985 Carrera 3.2 in Cape Town landed in West Sussex for roughly forty percent less than a comparable UK-market car. The trade was real. The shipping was material but knowable. The duty was a known unknown. The only unknown unknown — as always in this market — was the rand. This month, with the rand sitting near R23.5 to the pound, the same trade returns under five percent. Here is the arithmetic.

The classic-car trade has been arbitraging the SA–UK gap, on pre-1990 Porsches in particular, since 2014. The original trade was elegant: G-series 911s, including 3.2 Carreras and SC variants, were chronically under-priced in Johannesburg and Cape Town through the early 2010s, while the UK market — pulled by a global appetite for air-cooled 911s — was bidding the same chassis up by ten or fifteen percent a year. A 3.2 Carrera bought in 2015 for R1.1m, shipped, recommissioned, MOT'd and sold from a Henley dealer for £58,000, returned the kind of headline twenty percent net of all costs that drew non-specialist money into the trade.

The trade worked because three things were in alignment: a soft rand, a strong UK appetite, and a duty regime that, for cars older than thirty years (the UK historic-vehicle definition), reduced import VAT to five percent and import duty to zero. The car had to be over thirty years old at the moment of import. For 3.2 Carreras, that line was crossed in 2014–2018 depending on production date; for SCs, earlier; for 964s, only this year and next.

Today's arithmetic, in full

The same 1985 3.2 Carrera, in 2026:

The trade is, in 2026, marginal-to-negative on a Carrera 3.2 unless the buyer either does the work themselves (saving the commission) or stays patient enough to pick the right SA-side outlier. The Bureau's experience: it is the latter that pays. SA classics are not priced efficiently; the median ask conceals a long tail of one-owner, low-mileage, sub-median cars whose South African vendors have not posted them to UK-facing channels. Those cars still cross the spread comfortably. The median car does not.

The arbitrage is in the outliers, not the median. It always was.

What changes this

Two things have, since 2024, narrowed this trade: the rand has weakened against sterling by roughly fourteen percent (closing the GBP-denominated discount) and UK demand for early G-bodies has matured, with median UK asking down from £82,000 in mid-2023 to a softer £74,000 today. Either could reverse. A sharp rand recovery is unlikely on current fiscal trajectory. A UK demand recovery is more plausible — the same investors who chased 964s through 2023 are starting to look at the older 3.2 as the bottom of the air-cooled ladder, and a renewed bid there is, to a quant strategist, the obvious next trade.

For now, the bureau's view is that the SA→UK Carrera-3.2 trade is on pause. The same arithmetic on 964 Carreras (which crossed the thirty-year historic line in 2021) still works, slightly. The 993 — not historic-vehicle until 2025 — does not. The trade most worth running, today, is on 1980s W113 and W123 Mercedes — neither of which we have written up here, but both of which are the subject of a longer Bureau Notes piece due later this quarter.
