Measured across this library, a value with no Australian result behind it runs high about seven times in ten, by a median of ten per cent. Read this one as a ceiling rather than a midpoint.

Price history

Today $260,000 · modelled median at five years $309,703
Solid line: the value this library has carriedDashed from 2026: modelled · even money $256,992 to $380,293
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 ($209,492 to $443,904). 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 65/100, ranking 34 of 104 in the over $100k band. Demand durability is the strongest input, liquidity the weakest.
Running it costs about $12,650 a year (4.9% of value), which is what the economics score measures. All in, including the projected value change, it is $5,829 a year.
The model's five year median is $309,703, a +19.1% move, with the tenth percentile at $209,492.
Value is research, not a measurement. Treat the level as indicative and the structure as the analysis.

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.

Generation not established by the listing and the price band points at a 997.1 rather than this 997.2. DISCLOSED FAULTS: multiple transaxle oil leaks requiring a rebuild, engine case gasket leak, disintegrating dashboard foam, faulty bonnet switch
0 completed Australian sales of 1 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

The final Mezger GT3. Every GT Porsche with that engine has re-rated and the 997.2 is the most usable of them.

The case against

Track use is the norm for these cars. Provenance work is mandatory and priced into honest examples. There is no counted Australian sale under this value: the one 997 GT3 result on record, $185,000 in December 2025, cannot be placed as a 997.1 or a 997.2 from its listing, and if it proves to be a 997.2 this record falls to about $215,000.

The reason it is excluded is the generation

This record is the 997.2 - the 3.8-litre, 320kW, 2009-11 car, the last Mezger GT3. The listing does not state which 997 GT3 it is, and two things point at the earlier 997.1: $185,000 sits in the Australian 997.1 band and well below where 997.2 cars trade, and the disclosed fault list is heavy for a car five years newer. Counting it here would knock $45,000 off a 997.2 valuation on evidence about a different car, which is precisely the error this library has already shipped five times.

One line from the listing resolves it

- the model year, or 3.6 versus 3.8 - AND THE TWO ANSWERS ARE FAR APART. If it is a 997.2: the odometer adjustment at 63,930 against the 45,000 expected here is minus 2.8 per cent, so the sale normalises to about $190,400; the disclosed work - multiple transaxle oil leaks requiring a rebuild, an engine case gasket leak, disintegrating dashboard foam, a faulty bonnet switch - is roughly $24,000 of deferred cost, mostly engine-out and transaxle labour; a sound car is therefore worth about $215,000 and THIS RECORD SHOULD FALL FROM $260,000 TO $215,000. If it is a 997.1: the sale is a strong 997.1 result, says nothing about this record, and the $260,000 carried here remains what it has always been - a number with no Australian sale under it.

Until that is settled this record has no counted Australian evidence

And the value should be read as an estimate rather than a measurement.

The fault list is also evidence in its own right

A GT3 with transaxle leaks needing a rebuild and a leaking engine case gasket still made $185,000 at open auction, which is a useful read on how far this market will look past mechanical disclosure.

What we will not sell you
We will not price a Porsche 911 against an advertisement.

No Australian transaction stands behind this value. A spec-adjusted figure built on it would look precise and would not be, so the report is refused instead of sold with a caveat. That goes for this car and 87 others. Everything above is free and stays free.
