Just signed my weekend car('90 GTR) up with NRMA Classic yesterday after getting quoted around $2k from regular NRMA/Just Car for similar limited use.
$450 a year(after loyalty discount - roadside+CTP), $25k agreed value, $500 excess can use the car 10 days a month. Pretty happy that they could save me $1500+ and are always willing to increase the agreed value after mods/ market value increase.
