When I purchased my insurance I was 21 years old, and it covered $22,500 with AAMI. I had a brand new Corolla Ascent hatchback. I pay $750 premium and I think $1100 excess for a claim. Once im 25+ the excess with drop to $500 or so. I did another quote, hypothetically if I lived in my girlfriends suburb. If i did, insurance would be $1500 premium, same excess. The area has a huge influence.
