The pit inspectors do not know how you will be registering your unregistered or interstate vehicle.
When I took my 110 over the pits (the first time - with no immobiliser) they checked that it was newer than 25 yo before confirming I needed an immobiliser. No mention of concessional rego was made.
The requirement in WA is the immobiliser must self arm within 3 minutes of turning off the ignition - so not sure how that would work on a perentie without a key?
