I have had a rather bad experience lately. It's not a skyline, but hey it shares some heritage.
Origionally got defected for the car being 1 inch too low at the front, the highway coppers thought they'd give me a major defect notice for this "highly" dangerious modification which kills people left right and centre, since it was _so_ dangerious I was given 2 hours to drive home (on a weekend - so no chance of clearing the defect until it was a working day).
Enough of that and onto "regency".
Now I had stock standard springs put back in, went to the holden hill police station where the copper came and had a look and granted me an extension on the defect until I had the regency inspection.
Rocked up, and was done for approx. 30 items at regency, he had to get a 2nd piece of paper to fit them all on.
Such important things as "water bottle empty"... front eyebrow height too low by 2mm, yes that is 2 freaking milimetres, I will be watching the measuring very closely next time.
They want all of the turbo timer wiring presented in a bag at the next inspection!? Most of which was removed, but a few wires remained.
They reakon the top of the steering wheel "flexes", hell its a late 80's car I doubt any car from that period of time has a rock solid steering wheel.
There was some vaccum lines modified for the boost gauge, apparenty I need to return the vaccum lines to stock for whatever reasons.
As someone said above, sounds like the rear diff brushes are a popular item when looking for an easy defect.
There is a drain hole in the boot which i am 100% sure is stock from the factory, somehow this is a "defect" as well.
This is a clean car, and I certainly made my best efforts to be polite while there, so I'm not sure why all of these items were picked on.
Fun, fun fun.
