Phew, just did the ring around. 44 yrs old. 26K on a 350GT in Arcadia Vale (Newcastle) with AI Insurance quote was $1100. Bonus is they give you roadside assistance, no excess on windscreens and no extra to pay monthly. They will also cover my 18yr old as an unlisted driver. Oh, excess is $600.
NRMA: $1300
Famous: $1370
Just Car: $1900
Incidently I tried to add my 19 year son as a listed driver with NRMA and the premium was $9800 per year.
