Shannons are excellent.
Hmm WillC, I'd spend a few hours on the phone to Allianz, AAMI, etc and get some quotes then go back to GIO and tell them to f**k off or lower the premium. They should lower it a bit when presented with competing quotes.
Or switch to another insurer. I'm 23, car is financed, I've had multitude of speeding tickets and I'm only paying $1000/yr, and the agreed value I believe is $30k.
Also depending on what bank you are with, some banks have partnerships with Insurers, my Allianz is through Heritage Bank and saves me $200/yr.
Just avoid Swann, Youi and Just Car, they are not as comprehensive and will default on your larger claims.
