I disagree, I think Commodore sales have slowed appreciably since they announced the death of Holden.
The real sustainable target-market is the V6 models, with the V8's being only a niche which has increased in sales because you won't be able to get anything like it ever again ... and those sales have backed right off since the market was made aware that Holden's going to be killed in a few months.
They were basically holding the same sales-position, at least among proper cars, for the years prior. All the poor drivers that need SUV's to compensate-for (and amplify their) bad driving are becoming more & more numerous due to societal & policing attitudes, and that's where all the Falcodore sales went ...
