I reckon Holden was run like a mine site. Lots of chiefs making decisions based on nothing to do with reality. Have three meetings a day and change the plans each time as they realise they didn't work. Eventually a decision is forced upon them. Then they go broke.
Hence the dogs breakfast of naming models and not even following basic alphabetical order for models.
There would be people with brilliant ideas for cars that people wanted but the chiefs would have been scared of them because they were more intelligent so they transferred them to the cleaning team.
It really shows up now when trying to work out what is what 30 years after these cars were built. Holden, the dogs breakfast of model identification.
