Price history

Today $24,000 · modelled median at five years $26,007
Solid line: the value this library has carriedDashed from 2026: modelled · even money $19,122 to $33,318
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 ($12,917 to $39,907). 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 48/100, ranking 14 of 46 in the under $30k band. Scarcity is the strongest input, liquidity the weakest.
Running it costs about $6,650 a year (27.7% of value), which is what the economics score measures. All in, including the projected value change, it is $6,581 a year.
The model's five year median is $26,007, a +8.4% move, with the tenth percentile at $12,917.
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.

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 rarest way to own a Busso V6, with roughly 1,678 Sportwagons built against 2,973 sedans, in a fast estate body that has become fashionable since. Only two have appeared at auction anywhere in the last decade, which is the clearest measure of how rarely they come to market.

The case against

There is almost no evidence for this car anywhere. Two international lots in a decade, no Australian auction record, no local asking price on file, and the two overseas results differ by a factor of three. Running costs match the sedan on a car that is harder to sell, and wagon bodies normally trade below saloons.

Known faults and risks

Risk 2Timing belt and variator service costs
Risk 3Thinning parts supply for Busso V6 components

No Australian result

The GTA Sportwagon has no Australian auction record and no Australian asking price on file. Roughly 1,678 were built against 2,973 sedans, and very few reached Australia. The value here is inference from the sedan plus a scarcity premium, not measurement. INTERNATIONAL CONTEXT, and there is very little of it: only TWO Sportwagon lots appear in the entire record, and they disagree sharply. One made GBP6,264 at Anglia in November 2024; the other made EUR21,456 at Artcurial in June 2023, catalogued as a Break SW. Unconverted, those are roughly A$12,000 and A$36,000 for the same model a year apart. Two lots cannot be reconciled into a market level, so no clearance rate, direction or dispersion is claimed. What the wider fourteen-lot 156 GTA record does suggest is that the Sportwagon is not systematically cheaper than the sedan, which is unusual - wagon bodies normally trade below saloons. On this model the rarity appears to offset that, but two observations cannot price it.

What we will not sell you
We will not price a Alfa Romeo 156 GTA 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.
