I was quoted $1,800 for comprehensive (only about $60 less for 3rd party) insurance on 1987 AE82 Hatch CS (Single cam). Tt had to be insured for $3,300, I wanted to insure it for $2,000 but it wasn't possible because of the low km's. That was for me as primary driver (19 in August, no accident history and a bit over a year's driving experience).
When I went under secondary driver and put the car under my dad's name it went to $,1078 for the both of us comprehensive. As secondary driver you can drive the car whenever you want, you're not limited to like once a month or whatever it is. This is $1,078 for the both of us comprehensive with NRMA.
Maybe you could try putting the car under one of your parents' names or an older brother or something with more experience. Just give them a call and see how it goes.
