Personally, I'm losing patience with all the comments blaming wages, sales and cost of development. Yes those are factors, but they could have easily not been with some better business decisions by GM.
Wages for the factory workers were not excessive and would not have been an issue anyway if GM had followed through on a legitimate export strategy for the zeta platform instead of sabotaging Holden's every effort. Why did they even spend 1b developing a sedan at that point anyway when it was clear that the market was shifting to SUVs? In hindsight it would have been wiser to continue with the modified-opel-sedan way of doing things.
With the end of the VF, of course sales sucked big time as GM didn't have any competitive (new) RHD models and hadn't seriously developed anything since the GFC. The left-right hand drive cost argument is also exaggerated. If the car is designed properly then LHD or RHD build at the factory is a non issue. Even Holden was able to do that with our VEs and VFs. I honestly thought GM would wake up to themselves and ensure the next gen Camaro and Corvettes could leave the factory in either L or R configuration. Doing post factory conversions is too costly and made no sense what so ever. Extremely sceptical that 'GMSV' will ever happen in a meaningful way.
GM stabbed Holden and Australia in the back. Scum. I'll never forgive them for these last 10 years.
