Well, as @C.A.R. asked for an update here (because he really loves the V8 in it!)
The Z passed roadworthy, CPS paperwork signed by NDSOC, off to vic-roads, spent 1.5hrs there, not lining up either, but more trying to sort out the M-plates! long story, not for the interwebs.
Plates on, quick trip to get groceries:
I had taken the Z out a couple of times after it was first registered, mainly to my soccer games on Saturdays if the weather was dry enough, the roads get filthy around here with all of the roadworks.
