No GTV6 result was reachable in any archive searched. The nearest published Australian figure is a single unaudited Shannons price of $13,000 for a four-cylinder Alfetta GTV 2.0 in February 2019, which is a different model and is not carried as evidence for this one.
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.

Solid line: the value this library has carriedDashed from 2026: modelled · even money $39,081 to $58,085
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 ($31,032 to $67,162). 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 53/100, ranking 52 of 94 in the $30k to $100k band. Demand durability is the strongest input, risk resilience the weakest.
Running it costs about $4,570 a year (10.9% of value), which is what the economics score measures. All in, including the projected value change, it is $3,921 a year.
The model's five year median is $48,013, a +14.3% move, with the tenth percentile at $31,032.
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 2.5 Busso V6 in a 1,210kg rear-transaxle coupe, and the model has moved from roughly a $20,000 car to a $40,000 car over five years on the broader eighties Alfa revival. Twenty-two thousand three hundred and eighty were built worldwide across the two series, and Australia took them new in right-hand drive.

The case against

No GTV6 result appears in any archive this research could reach, so the value here is placed rather than measured. A transaxle rebuild is $10,500, rust is $12,500 and the clutch lives in the transaxle at $6,250, which on a $42,000 car means two bad findings put a buyer underwater.

Known faults and risks

Risk 1Four-cylinder Alfetta GTVs converted to V6 and sold as GTV6s
Risk 2A crunchy second gear, which means a $10,500 transaxle rebuild
Risk 3Any twin-turbo provenance claim is unproven without factory or AROCA paperwork
Rust - sills, floors, rear arches, front suspension mounting points, screen surround$12,500
Full transaxle rebuild - price any car with a crunchy 2nd gear as needing this$10,500
Cylinder head oil leaks and valve-guide wear$6,500
Clutch, which lives in the rear transaxle and means dropping it$6,250
Dash cracking and interior trim, correct parts scarce$5,500
L-Jetronic ageing - AFM, injectors, fuel pump, brittle wiring$3,500

The only published Australian figure anywhere near this car is for a different car

Shannons sold a 1980 four-cylinder Alfetta GTV 2.0 for $13,000 at its Melbourne Summer sale on 18 February 2019, lot 5. That is one published price, read through a summarising layer rather than audited lot by lot, it is seven years old, and it is a four-cylinder car rather than a GTV6 - Shannons left the auction business in November 2023 and its lot pages have been taken down, so nothing more recent exists to replace it. It sits on this page for one reason. Against a $42,000 V6 it puts the premium for the six at roughly threefold, and a threefold premium is exactly the incentive that gets four-cylinder Alfettas converted and sold as GTV6s. Verify the engine and the build before anything on this page applies to a specific car.

The transaxle is the cost Centre

A full rebuild is $10,500 and the practical rule is to price any car with a crunchy second gear as needing one. The clutch lives in the rear transaxle as well, so replacing it means dropping the assembly, at $6,250. Add structural rust at $12,500 - sills, floors, rear arches, front suspension mounting points, screen surround - and two findings on a $42,000 car put a buyer underwater before the cylinder head oil leaks at $6,500 and the ageing L-Jetronic at $3,500 are counted at all.

The Australian Twin-Turbo story is not established

A small run of Australian-market twin-turbo GTV6s is asserted by a single Wikipedia sentence and by nothing else this research could find. The builder, the power figure, the year and the quantity are all unverified. Treat any twin-turbo provenance claim as unproven until it is documented by Alfa Romeo Australia or by AROCA paperwork, and do not pay a premium for it in the meantime. Australian assembly of Alfettas is likewise unconfirmed in either direction and is not claimed here.

What is established

22,380 GTV6 2.5s were built worldwide across the two series, 11,468 from 1980 to 1983 and 10,912 from 1983 to 1987, with the right-hand-drive share not found. The car was sold new here in right-hand drive, though the local volume and price were not. Series 2 cars from 1983 are generally preferred, and the trend is up solidly.

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