In a "perfect world" people could buy whatever they want, and issues like balancing engineering, manufacturing and marketing costs vs return on investment wouldn't be an issue.
Why was there a VE V8 manual wagon, but no VF version?
The answer isn't that hard to find.
VE was developed in a period of prosperity for large local cars, when many thousands were still being sold each month. There was easily enough sales to justify covering many of the various sales possibilities- even the low volume ones like this one.
The large car class has since dived, and more and more people are migrating to auto's as well.
Some have gone to other brands. What have you missed out on doing so? No "grunt"? Bit small? Handles like a truck?
End of the day you ALWAYS have to weigh up what you gain and what you lose between different options. Rarely ever will one car tick every single box!
