A Club Permit can be issued to the vehicles in the following categories:

veteran vehicles – manufactured before 1 January 1919
vintage vehicles – manufactured after 31 December 1918 and before 1 January 1931
classic and historic vehicles – manufactured after 31 December 1930, but more than 25 years before the date of the application for a Club Permit.
These categories can include trailers, heavy vehicles and modified vehicles such as street rods. Replicas of vehicles eligible for the above categories may also be issued with a Club Permit. Replica vehicles will be issued a club permit under the classic and historic vehicles category irrespective of the vehicle being replicated.

A replica means a light motor vehicle that is an individually constructed vehicle that resembles, as close as practicable, the appearance and dimensions of the production vehicle on which its design is based.

I was contemplating on doing a K20 vtec build as I have an engine that I picked up 2 years ago during the pandemic, still sitting in my garage getting lonely. I was
hoping to put it in a round nose but that would require a f/glass extended front end. From what I've since read, they are not street legal in Australia. I could always
mount the radiator in front of the grill , not that good a look though. I think my only option is to find some more options.
