Nissan Skyline GT-R V-Spec

Forty-six lots worldwide, 67 per cent sold and 59 per cent since 2024. No direction is read from them, because the R34 range runs from a base GT-R to a NISMO CRS and the spread within a single currency is over three times from upper quartile to lower - in a sample that mixed, movement is which variant turned up rather than what the market did. British sales of ordinary cars sit unconverted between GBP78,750 and GBP121,500 across 2023 and 2024.

A white 1999 car sold on Collecting Cars for A$150,000 in Cairns. 166,659km against the 91,500km this library expects of a 1999 build, and substantially modified: Apexi Power FC management, Tomei Poncams and adjustable gears, Garrett 2860-7 turbochargers, Nismo fuel pump, manifolds and clutch, Splitfire coils, K&N pods and a Gannador titanium exhaust, 459.8hp claimed on the dyno.

Deriving the number from the transaction and then reporting how close the number came to the transaction proves nothing: a value back-solved from a result can never be tested by it. The value here is built from four sources that have nothing to do with Cairns. Collecting Cars' own 2026 price guide puts the APAC starting point near A$170,000 for higher-kilometre V-Specs, which is a floor rather than a middle. The 2018 Shannons pair in the list above dates the Nur premium at about 1.6 times a standard V-Spec, and the M-Spec Nur entry at $345,000 divided by 1.6 gives $215,600. The April 2018 V-Spec at $90,000, escalated on the trajectory the Nur results themselves describe, gives about $216,000. Australian V-Spec II results average $269,800 across four sales, and a V-Spec I trades some fifteen per cent under a II, giving about $229,300. The three central figures average $220,200 and the value is set at $220,000.

The Cairns car was run through the valuer against that independent $220,000 on 15 August, the day before the lot closed, and priced at $155,100. It made $150,000 on the 16th - 3.4 per cent high, on a car carrying a 29.5 per cent adjustment. That figure went up before the hammer rather than being written afterwards, which is the only reason it is worth reading. It is graded on the track record as a line ball and not as a hit: the published tolerance for a predicted price is three per cent either way, and this missed it by four tenths of a point.

$280,000, $205,000, $195,000, $215,000, $220,000. The first cut removed a fabricated kilometre penalty and a history that rose in every period. The second removed a double charge where a catch-all modification row was added to the itemised rows pricing the same changes. The third followed a fix to the model, which had no row for camshafts, turbocharger upgrades, fuel and ignition work, clutches or cooling. The fourth stopped back-solving from the sale. Alongside it the variant span was corrected: the V-Spec I ran 1999 to 2000 and 4,289 were built, where this record previously claimed 1999 to 2002 and the 11,578 figure that covers every R34 GT-R ever made.

No Australian V-Spec II record exists yet despite four recorded local results, and until one does, buyers of the dearer variant have nothing here to read.

Everything from here down was written on 27 August 2026 and supersedes the value, not the call.

$164,000 at Tinderbox TAS in June 2023; $177,000 at Ingleburn NSW in July 2023 at 43,751 kilometres; $365,000 at Mitchelton QLD in October 2024 at a documented 6,846 kilometres; $192,000 at Sydney NSW in March 2026 at 106,771 kilometres after a full respray and a 3.5B auction grade; and $171,000 at Rowsley VIC in May 2026 at 75,928 kilometres with a TH400 three-speed automatic fitted in place of the six-speed. With the Cairns car that is six.

Distance and date correlate at PLUS 0.77 in these six cars - the later a car sold, the more kilometres it carried. This library's usual method works because date and distance are normally uncorrelated within a sample and therefore separate cleanly. Here they do not. Fitting both terms returns 19 per cent a year of appreciation on six points, and 37 per cent on five, which is the signature of two regressors dividing up one signal rather than a market.

Minus 3.25 per cent per 10,000 kilometres, R-squared 0.36, and $181,805 at the 90,000 kilometres this record expects.

Three of its four legs assumed a V-Spec I trades about fifteen per cent under a V-Spec II. Three Australian V-Spec II results are now recorded below and, normalised to 90,000 kilometres, they average $262,167 against $182,000 for the V-Spec I.

An assumption applied three times over is why a derived number came out 19 per cent high.

This record carried 1.4 per cent per 10,000 kilometres; the six sales measure 3.25 and it is now set to 3.2. At 3.2, the plus-or-minus 12 per cent cap in the appraiser binds beyond 37,500 kilometres either side of 90,000 - and four of these six cars are outside that band. The cap, not the coefficient, is now setting the adjustment for most of the fleet. That is a standing decision, not a defect this record can fix.

The Tinderbox car shows three different odometers - 28,729 kilometres on the listing header, 16,870 on the fitted Nismo cluster and 11,859 on the original cluster - so its distance is unusable even though its price is real. The Rowsley car has a different gearbox from the one this record describes.

Three results, a 44 per cent premium and its own distance profile is enough to stand alone, and folding it in here is what produced the error above.

It was right: at 3.2 per cent per 10,000 kilometres the twelve per cent rail bound beyond 37,500 kilometres either side of 90,000, which on a car whose counted results run from 43,751 kilometres is most of the population. The model now runs a constant-elasticity curve with 3.2 as its slope at the expected distance, so at 43,751 kilometres it returns $227,714 rather than $207,200 and at 150,000 it returns $159,691 rather than $162,800. The coefficient this record measured for itself is untouched; what changed is that it is no longer switched off past a fixed distance.
