The case for and against
Australian 930 money roughly doubled between 2018 and 2023, and the flattening since 2024 has been confined to imported and four-speed cars rather than Australian-delivered G50s. Australia visibly ran ahead of the estimate book on this model, which is what a market with more buyers than cars looks like.
The only published Australian result is $137,000 for a left-hand-drive 1979 car in November 2020, and the value here is $300,000. Detonation writes off a 930 engine at $60,000 to rebuild, and rust repair on the wide-arch body is $47,500.

On 7 September 2026 a 1982 3.3 made $201,888 at Melbourne — the first verified right-hand-drive 3.3 result this record has ever had, against a published call of $145,000 that was 28.2 per cent under it. The instinct on a miss that size is to cut the value. Work it through and the opposite is true. Unwind that hammer through this record's own two hardest terms and nothing else: the distance coefficient of 1.9 per cent per 10,000 kilometres against the 45,000 this entry expects, and the twelve per cent this library docks an import on a model Porsche sold here new. At 167,712 kilometres the distance term is minus 23.3 per cent, and undoing both lands at $299,171 against a carried $300,000.

The model will not actually use minus 23.3, because it caps any odometer adjustment at twelve per cent either way; at the cap the same unwind gives $229,418. The $299,171 is what this record's stated coefficient implies with the cap lifted, not what the valuer outputs, and quoting it without saying so would be picking the convenient rate.
No allowance is made in it for the four-speed gearbox, and this entry states that a G50 five-speed is worth 40 to 60 per cent over one, nor for the turbo and exhaust conversion. Both of those would push the implied base for a stock five-speed car higher again, which leaves two live readings and the record does not yet choose between them: either $300,000 is conservative for a documented Australian-delivered five-speed, or the 1.9 per cent distance coefficient is too steep and is doing work the gearbox and origin terms should be doing.
The call took a 52 per cent discount off the carried value. The car's own cells — high distance, import, four-speed, converted turbo — account for the gap between the two figures almost exactly. The discount was applied twice.
Shannons ran a 1985 Australian-delivered 930 Turbo 3.3 in its timed online auction of 15 to 22 August 2023 - 149,363km, White Gold over dark burgundy leather, electric sunroof - with a published estimate of $340,000 to $360,000. The sold price was never published, Shannons left the auction business that November, and the archive was stripped, so the $350,000 in circulation is a midpoint of an estimate. It is not a result and it does not set this value.
A left-hand-drive 1979 coupe made $137,000 in the Shannons Spring Online auction closing 18 November 2020. Different specification, different steering side, different point in the cycle; it brackets the bottom rather than describing the middle. The only other local figure is a $349,990 dealer asking price on a 1988 Slant Nose Cabriolet, and Flachbau cars are a separate and narrower market from the standard coupe.
The MY1989 G50 five-speed is worth 40 to 60 per cent over an equivalent four-speed, Australian delivery a further 25 to 35, and a replaced or rebuilt non-original engine costs 20 to 30. With an estimated 45 to 60 per cent of local 930s imported from the United States, Britain and Japan, any single number on this model is really a number for one cell of a four-way grid.

The evidence on this model is thin and the report says so on its cover. Read a complete one on a real car first. Seventeen sections, no account, nothing to pay.
One line of email when this desk publishes a call on a Porsche 911 Turbo 3.3, or records a new Australian sale of one. Nothing else, no schedule, and on a quiet model you may hear nothing for months, which is itself worth knowing about a car you are chasing.
