They joys of owning an import.
Rules re dickson:
as of about 4 months ago ALL imports have to go through dickson as part of their crackdown. Before that if it was a car from the ACT anywhere could do the inspection. Interstate "prefers" you to go through dickson. Still didn't have to. I got my GTR and had the inspection done in a place in fyshwick (canberra car).
My mates s15 was done and Ultimate tunes and passed there.
Unfortunately its just how dickson runs at the moment. Don't know if they will back off any time soon....
