Oh Moo, I'm so sorry to hear this but so glad that you are ok
As to your claim, my experience is you will be paid whatever the "Agreed Value" or "Market Value" is on your most recent insurance policy that you paid and most policies seem to default to "Market Value" unless you specify (and pay increased premiums for) the "Agreed Value". Unfortunately, whatever that amount is, that is what you will get paid and in my experience it's usually lower than the real market value (ie. what you would get if you sold it).
With the hail storm, my car was written off. It was less than two years old, therefore I could choose to have it replaced, or I could take the "Market Value" (as that is what my policy was for, not "Agreed"). I ended up getting it replaced, as even though the car was quite young and retailed at around $50,000, it's market value was only $31,000
I have a feeling they used Red Book, but I think this can vary from insurer to insurer.
The lesson I learnt from this experience was to have an "Agreed Value" on my policy and not go with market, as the loss, particularly on a new car, is substantial. I'd ring your insurer and ask, they should be able to indicate over the phone what you will be paid. If a Loss Adjuster has assessed your car, they should be able to tell you what the payout is going to be fairly quickly.
