Ok.
The link that UKSqueezea posted was to an ebay listing for the Brock Marlboro Torana, which Scalex announced but withdrew due to tobacco advertising (cos they didn't realise it was baccy related when they announced). Scalex will still be releasing a Brock Torana but it will the red, white and blue livery that he ran with his brother Phil. Also, it was listed at a starting price 5 quid, from memory.
It's a typical pre-release listing from one of the forum sponsors who moves a large majority of their stock on eBay.
Does it make any more sense now? Possibly not. It is important to understand the near god-like status that Peter Brock had in Australia and the fact that the Marlboro car was his most widely remembered livery from the era.
