A higher excess reduces your per year fee .... .. corolla is high insurance because of how many are on the road It is generally cheaper to insure a Porsche than a standard car because of claims Insurance goes on Age ... Sex ..... Location .. then car and then amount of cars they have insured and how many claims are made on that car in that area that you live Just Car (AAMI).. will insure anyone but excess is crazy Even rating One lifetime on a standard corolla ascent is around $900 upwards for full insurance cover in most area's of melbourne So shop around ... check interstate companys like Suncorp which is in queensland i think AAMI is about the best .. If you live at home insure in your parents name .. because insurance doesn't care who owns the car
