Mate they churned out commodores very successfully in this country for 39yrs, including for 20 odd years after the VS. Not many nameplates globally last anywhere near as long. Hardly a failure.
Not quite sure you get where the industry failed.
Australian's took quite a while to become educated in what car building was all about. Honestly take a look at the shite Holden, Ford and Chrysler were serving up to us (3 speed column shift manuals, vinyl floor mats, no radio, bench seats, no heaters, the list goes on) and then look at what overseas manufacturers were pegging against us at the same time. Body panel fit was very poor in Aussie cars while it was much better in overseas cars, paint was deplorable on ours as well and by the time our makers caught up the horse had most certainly bolted and people's buying attitude had already swung towards overseas models. From there our 3 makers were simply trying to catch up but had already lost the fight long ago, and truthfully, they already knew it.
The thing is that us older guys love the idea of loving our own product and being patriotic to our country but the Gods honest truth is our own casual lifestyle was our own downfall and now we are paying for that.
Anyway this is way off topic and door alignment is where this thread is all at. For me anyway.
