One publishable Australian result: $374,600 for a 2018 GT3 Touring through Collecting Cars in June 2023. A Lorbek retail figure of $359,990 is dealer money rather than a hammer price.
Measured across this library, a value resting on a single Australian result runs high about six times in ten, by a median of five per cent.

Solid line: the value this library has carriedDashed from 2026: modelled · even money $296,731 to $403,992
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 ($252,510 to $456,429). 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 62/100, ranking 49 of 104 in the over $100k band. Demand durability is the strongest input, risk resilience the weakest.
Running it costs about $19,570 a year (5.4% of value), which is what the economics score measures. All in, including the projected value change, it is $27,693 a year.
The model's five year median is $345,803, a -4.6% move, with the tenth percentile at $252,510.
Value calibrated to a thin record. Treat the level as provisional.

At least one recorded transaction plus a source. Direction is sound, the exact level less so.
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.

No date is published against this figure and it is excluded from this record, which is a dated series; it is shown because it is real published money.
1 completed Australian sale of 2 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

It never depreciated below its $327,100 Australian list price, and a single-owner Touring made $374,600 through Collecting Cars in June 2023 to lead every Australian sale on that platform that month. Manual now outranks PDK and the Touring package is the strongest single option on the car.

The case against

The model peaked in 2022 and 2023 and eased 10 to 15 per cent through 2024 and 2025 as the 992 GT3 arrived, stabilising in 2026 at roughly its 2023 level plus inflation. A carbon-ceramic disc set is $45,000, so steel versus ceramic has to be established before any of these numbers apply to a specific car.

Risk 2Track use, and the clutch on a tracked manual

One auction result and one dealer sale, and they agree

A single-owner 2018 991.2 GT3 Touring made $374,600 through Collecting Cars in mid-June 2023 and led every Australian sale on that platform that month. Lorbek separately marked a 2018 six-speed manual sold at $359,990 - Guards Red, 22,620km, described as the last of the series, front lift, Sport Chrono, full paint protection film, carbon interior and engine-bay packs, never tracked, full Porsche Centre history, both keys. The second is dealer retail with no date published, not a hammer, but two figures within four per cent of each other on the two most wanted specifications is a usable read rather than a guess.

This car never depreciated below list in Australia

Porsche Cars Australia listed it at $327,100 before on-roads from March 2017, $33,900 up on the 991.1 GT3, and the money has sat above that ever since. It peaked in 2022 and 2023, eased 10 to 15 per cent through 2024 and 2025 as the 992 GT3 arrived, and stabilised in 2026 at roughly its 2023 level plus inflation. That is the shape marked here.

Imports are irrelevant on this one,

Which is rare in this tranche. A near-new Australian-complianced car is cheaper than importing one, so essentially every local GT3 is one of an estimated 90 to 160 Porsche Cars Australia deliveries across GT3 and Touring.

The brakes are the valuation trap

A carbon-ceramic set is $45,000 and changes the maintenance liability more than any other option.
