Five Australian results inside thirteen months, $56,500 at 136,978km to $107,500 at 12,802km. These prices reach this library through a third-party compiler rather than from the selling house: Collecting Cars publishes the car, the date, the suburb, the odometer and the condition report, and puts the final figure behind a login. They are carried as evidence on that basis and the provenance is stated here so it can be weighed.

Price history

Today $85,000 · modelled median at five years $83,842
Solid line: the value this library has carriedDashed from 2026: modelled · even money $75,497 to $91,780
The green band is the even-money range and the one to plan on: half of outcomes land inside it. The pale band behind it bounds eight in ten ($67,977 to $98,933). The path is this model's own: it starts along the momentum of its recorded history and bends toward its projected median as the horizon lengthens, so no two cars share a future curve.

The verdict

A defensible case with reservations. Scores 56/100, ranking 41 of 94 in the $30k to $100k band. Ownership economics is the strongest input, risk resilience the weakest.
Running it costs about $8,170 a year (9.6% of value), which is what the economics score measures. All in, including the projected value change, it is $9,524 a year.
The model's five year median is $83,842, a -1.4% move, with the tenth percentile at $67,977.

Scored against every recent Australian sale this library holds, half its values land within 11.2 per cent of the price paid and the rest miss by more, in either direction. Projections are therefore damped toward flat in proportion to how little is known, and the plausible band is never narrower than the error the model is known to make.

5 completed Australian sales of 5 rows. Rows marked asking, no sale, or context are shown for honesty but do not count toward the evidence grade: an ask is not a transaction, a pass-in is a refusal, and a provenance or overseas result does not price the ordinary local car. The badge on every row is computed by the same rule as the grade, so the two cannot drift apart.

No forecast is used to compute the hurdle. It is the purchase, the duty, any premium and 5 years of running cost, grossed up for the cost of selling and spread back over the hold. The projection it is measured against is the weakest number in this product and is drawn that way in the chart above. Transport, finance and any restoration spend sit outside it.

The case for and against

The case for

Five Australian figures inside thirteen months show low-kilometre cars firming, with a 12,802km example at $107,500, about 52 per cent below its $225,000 list after eleven years. A 412kW twin-turbo V8 wagon that will carry a family has no real substitute at $85,000.

The case against

A pair of hot-V turbochargers is $20,000, a timing chain tensioner job is $11,500 with the engine out and the air suspension is $3,500 a corner, and stacked together that liability can exceed what a high-kilometre car is worth. The same generation spans about 1.9 times on odometer alone, so one wrong comparable moves the answer by tens of thousands.

Known faults and risks

Risk 1Cold-start rattle means a timing chain job at $11,500, engine out
Risk 2Adaptive air suspension leaks at $3,500 a corner
Risk 3High-kilometre cars can carry a repair bill above their value

The best-evidenced car in this tranche, and still not evidence this page can carry

Five Australian auction figures sit inside thirteen months: $107,500 on a 12,802km car, $88,888 at 68,411km, $80,000 at 70,264km, $63,000 at 91,488km and $56,500 at 136,978km. All five are carried, and five results inside thirteen months makes this the best-measured German car in the expansion. Read as a set they say something no single figure can: this model is priced almost entirely on the odometer, at a spread of about 1.9 times inside one generation.

Read the rest of the evidence notes (5 more)
The coefficient did not match that sentence and now does

The field carried kmPct 1.8, the library's own median, on a record whose whole argument is that distance prices the car. Fitted across the five sales, each indexed to 2026 so a falling market is not read as distance, the slope is 5.5 per cent per 10,000 kilometres with an r-squared of 0.87: $107,500 at 12,802km, $88,888 at 68,411km, $80,000 at 70,264km, $63,000 at 91,488km, $56,500 at 136,978km.

The coefficient moves 1.8 to 3.8,

Which is the fit shrunk toward the library median at five observations rather than the raw slope, on the rule the 981 Cayman set.

The value of $85,000 is held

It is quoted at the 55,000 kilometres this record expects and the fit returns $90,500 there, so the carried figure is already the conservative end of the set.

The market is splitting in two

Low-kilometre cars have bottomed and are firming, and the 12,802km car sold about 52 per cent below its $225,000 list after eleven years, which for a German performance wagon is remarkable. High-kilometre cars are still falling, because the repair overhang is real. A pair of hot-V turbochargers is $20,000, a timing chain tensioner job is $11,500 with the engine out, and the air suspension is $3,500 a corner. Stack those against a car that sold at $56,500 and the liability can exceed the asset.

Grade on history and distance, not on year

A live retail 2015 car at 192,201km asking $55,000 is optimistic beside a car with about 55,000 fewer kilometres that sold at $56,500. Audi Australia does not break out RS6 volumes, so the delivery figure here is a low-confidence estimate.
