Interestingly, someone is running a Subaru Forester this Sunday, not normally a quick hillclimb vehicle.
(There are three WRXs running as well)
You can see the entry list at https://evententry.motorsport.org.au/v2/events/4472
This is an historic event, so some very interesting historic cars running as well.
