Here's a couple of nice wrap ups for the VT-VX and VY-VZ:

By the 'market changes forever' bit I assume that is the rise of the SUV which Ford Oz timed perfectly with the Territory.
Geez Holden screwed the pooch with the Alloytec. Just as much as they absolutely nailed excellent product planning with the VT - Ford were having their turn with the pooch with AU1 at the same time. Engineering wise, I'll have the AU any day of the week, not much fun having a car that alters its rear suspension and steers with the rear on limit (fixed VXII).

Not being much of a Commodore historian it's been fun to see how the cars developed. To my way of thinking these models are the modern day HQ-HZ and are significant Australian cars.
Dr Terry, do you have any info on how the mechanicals/models changed over VT to VZ? I think the major rear suspension fix was VXII as stated above.
