A dust‑covered Holden VL Walkinshaw Commodore has surfaced in Adelaide, drawing intense interest from collectors who say untouched examples almost never appear on the open market.

The car is sitting inside one of the city’s premium showrooms, surrounded by high‑end marques — but it’s the unassuming layer of dust that has stopped enthusiasts in their tracks.

The vehicle is one of just 750 Walkinshaw Commodores ever built, all finished in Panorama Blue and fitted with the now‑iconic plastic body kit that earned nicknames ranging from “the Batmobile” to “the plastic pig”.

The model was created after Holden’s split with Peter Brock, with the company turning to Tom Walkinshaw to produce a new race‑ready special.

His Bathurst pedigree with Jaguar cemented the car’s place in Australian motorsport history.

The car — number 82 — has never been registered and was hidden away for decades before being consigned to Richmonds for sale by expressions of interest.

Holden fan Dave described it as “the holy grail”.

The car is expected to fetch close to $750,000, making its untouched condition part of the appeal.

The dust remains deliberately undisturbed, a visual reminder of its rarity and the reason it now sits front and centre among some of the world’s most famous automotive brands.
