Put in the asking price and the odometer reading. You will see what this model should make at that reading.
No Australian sale stands behind this value, so treat the figure as indicative.

What moves the price on this model
Condition, history, originality, ownership, delivery and modification multipliers apply to every car in the library. They are applied automatically when an advertisement is analysed, and the schedule is set out once, on the analyser page.
Projected value in five years
The case for and against
The 3.2 Busso V6 is the last of a celebrated engine family and this is the sharpest saloon it was fitted to, with a manual gearbox and a Q2 limited-slip differential that transforms the front end. Around 2,973 were built and very few reached Australia officially, so a good manual example is genuinely hard to find here.
Running costs are brutal relative to value at 33.8 per cent of the car a year, dominated by a timing belt service costing several thousand dollars every three to four years. There is no Australian auction record for the model at all, so the value rests on asking prices, and internationally the same car sells for roughly half the Australian level. Parts supply for Busso-specific components is thinning.
Known faults and risks
Similar cars, and what they cost to run
Asking prices only, no auction result. Private sellers were asking $24,900 in Victoria for a 146,000km manual with the Q2 limited-slip differential and full history, and $24,000 in Queensland for a 160,000km Rosso Miro car that had already taken a deposit. A third Victorian car, an Auto Italia class winner, was listed without a published price. Those are asks rather than transactions, and no 156 GTA has come to Australian auction, so this is the weakest grade of evidence in the library.

Fourteen lots and 71 per cent clearing. Eight British sedans sold unconverted between GBP4,760 and GBP9,450, median near GBP7,263. Australia values this car at roughly double the British level, which is the same shape the S2000, Integra Type R and R35 GT-R show between those two markets. One British result at GBP24,467 in July 2023 was 2.9 times its contemporaries and is set aside; nothing else in the record comes near it and the catalogue gives no reason for the gap. No direction is claimed - fourteen lots across eight years cannot support one.
Alfa Romeo did not publish definitive GTA numbers, and the Australian delivery count is inferred rather than sourced. Several Australian cars are private imports from Britain rather than local deliveries, so the local population is larger than the delivery figure suggests - one of the listings above says so explicitly.
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.
One line of email when this desk publishes a call on a Alfa Romeo 156 GTA Sedan, 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.
