I just got my renewal notice for my car insurance last week. My premium has gone up 17%, from $948 to $1108 and my excess went up 160%

, from $550 std exc. to $625 + $800 vehicle exc.
I rang them to find out why and they said yes we had a price increase and because I drive a V8 I now have the extra $800 vehicle excess.
I am rating 1 and 47yrs old. The car is a ford BA 1 tonne RTV v8.
This is just highway robbery. I could maybe understand it if I was 18 driving an XR8 or GT or something but on a 1 tonne ute.
So its time to let the fingers do some walking.
