Price history

Today $240,000 · modelled median at five years $314,293
Solid line: the value this library has carriedDashed from 2026: modelled · even money $271,022 to $376,562
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 ($232,028 to $432,675). 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 72/100, ranking 7 of 104 in the over $100k band. Demand durability is the strongest input, liquidity the weakest.
Running it costs about $6,950 a year (2.9% of value), which is what the economics score measures. All in, including the projected value change, it is -$5,509 a year.
The model's five year median is $314,293, a +31.0% move, with the tenth percentile at $232,028.
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.

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 most charismatic Group A Holden - Brock's own homologation special, one colour, 502 built - in a class where every measured comparable has appreciated. Scarcer than the VL and carrying the stronger name.

The case against

The value rests entirely on research and dealer asks; no public auction transaction verifies it. Single-colour production makes clones easier and originality checks matter more than on any other Holden here.

The Blue Meanie

502 cars built by Peter Brock's HDT in 1985-86 to homologate the VK for Group A, every one in Formula Blue, with the destroked 4.9-litre V8 sized to the class limit. It is the most instantly identified of all the Group A Holdens and the one with Brock's fingerprints most directly on it.

No published transaction in the searchable record

Like the VN Group A, the car changes hands - dealer listings and club sales run well into six figures - but no named auction level surfaces publicly, so this value is research positioned against the VL Group A SV's measured $200,000: the VK trades above it in the current market because Brock-era HDT provenance outranks HSV's first car in collector priority, and pass-the-parcel low-km examples have been asked near $400,000.

The spread is the story

Driven examples with history sit far below the delivery-kilometre trophies, and the model's single colour makes originality of paint one of the few visible separators.

Floor markers from the copy market

A VK Brock SS Group A TRIBUTE made $69,000 at Shannons in April 2021 - what the look alone is worth - and an HDT VK SS with Group A specification unconfirmed made $191,500 in August 2022. A verified Blue Meanie sits above both, which is what this value says.

What we will not sell you
We will not price a Holden Commodore SS Group A 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.
