Alright I'll give to you on a base technicality.
It's officially called the Brock Director.
Holden did not authorize or approve Peter Brock's car because he insisted on adding (and broke his lucrative association with Holden/GM), an 'Energy Polarizer' to 'enhance' performance properties of the vehicle. The pseudoscience he marketed was ridiculed by car manufacturers and soon his racing colleagues would soon disassociate from him. Only twelve of them were produced for an extravagant price and were not even compliant to Australian certification and were not allowed to be exported. He ruined his reputation even though he was Australia's favorite & legendary race car hero.
Like an Aussie 959, rare & convoluted history.
