OK Big thank you to Trav, the STI is now insured with RAC.

Age: 19
Insurer: RAC
Car: MY05 STi
Agreed Value: $25,000 (went to 20k and changed the ~$80, to me its worth keeping it higher)
Cost: $1730 P/A
Excess: $1200 total (650 basic + 550 age).

Now to get rid of this FMIC..

Thanks to everyone again,

Lachy
