Odometer only. Colour, options, history, condition and the photographs move it further, and that is what the report reads.

What moves the price on this model
Condition, history, originality, ownership, delivery and modification multipliers apply to every car in the library. They are applied automatically when an advertisement is analysed, and the schedule is set out once, on the analyser page.
Projected value in five years
The case for and against
A 555-car factory limited edition with a balanced engine, a titanium exhaust and carbon-backed Recaros, none of which came here new. The one chassis this record can track went up 2.2 per cent over twenty-six months while being driven, which is more than most of this library can say.
Four Australian sales in four years on a car whose price is set by build number and paperwork rather than anything measurable - price correlates with distance at plus 0.99, which is to say the sample is too small and too varied to fit at all. Every car is a Japanese import, and an S203 claim without the build plate should be assumed to be an ordinary STI.
Known faults and risks
Similar cars, and what they cost to run
The GD STI entry already set the S204 and the Spec C Type RA aside as different variants; the S203 results were not marked and were being counted as ordinary comparables. STI Japan built 555 of them, none came here new, and every Australian car is an import. The four results are $33,771, $34,500, $44,006 and $52,500.

Build number 440 of 555, Crystal Grey Metallic, imported in April 2022 on a Japanese auction grade of 4B, sold at Cranbourne West on 17 June 2023 showing 80,437 kilometres for $33,771, and again at Beecroft on 2 September 2025 showing 88,553 kilometres for $34,500. Both lots state the build number. Both carry the same Ohlins DFV coilovers, the same Prova air-oil separator and blow-off valve, the same Defi boost gauge and the same Python security system, and both note the original S203 suspension accompanying the car.
On 8,116 kilometres actually driven - the only repeat sale in this library where the car was used rather than stored. It is the third in a row to come back up, after the 944 Turbo at plus 2.3 and the AP2 S2000 at plus 13.1.
Fitted across the four lots, price against date implies about minus $4,100 a year. But those four lots are three different cars at three different build numbers on three different suspension setups, and the one car that can be tracked went up. A four-point cross-section cannot separate the market from which particular car happened to sell; a repeat sale does not have to. The direction is taken from the chassis and the level from the two most recent results.
Price correlates with the odometer at PLUS 0.991 across the four results: the 129,020-kilometre car made $52,500 and the 80,437-kilometre car made $33,771. Nobody should read that as distance adding value. What it says is that on a 555-car limited edition, build number, originality of the suspension and the completeness of the Japanese paperwork swamp the odometer entirely. The penalty is set at 1.0 per cent and is nominal; fitting the observed sign would be arithmetic, not valuation.
A larger turbocharger, a titanium exhaust, a retuned ECU, precision-balanced internals, adjustable dampers, reinforced springs, thicker anti-roll bars, front and rear strut braces, bigger brakes, carbon-backed Recaros and a 260km/h speedometer. It is not a trim level.
And is an inference from four Australian sales of a 555-car run, not a count. SOURCING: auction lot pages read in full, one to one against each result.
