Good tip, although in checking the PDS there are two gotchas with their lifetime new for old. 1) They have to be able supply the new for old car within 90 days of deciding it is a loss. If they cannot because of the Tesla supply chain, you end one with something that is in their opinion a similar make and model. 2) You need to be the first owner of the car to be eligible. My car was owned by my employer and driven by me for the first 9 months. So that rules me out.
I have now got 9 Quotes. With GIO you can achieve the lowest premium largely because they allow you to crank up the excess way higher than the other companies, including their parent Suncorp. Like
@Stratman suggested this yields very low premiums. If I max out the excess to $3200 it gives a $630 premium in my case. I will actually choose an excess more mid field I think. Thanks for the tips.
