So sorry to see the damage and hear it is probably totalled. Does your insurance cover it, or are you S.O.L.?
I recently switched my insurance company. I believe my previous policy covered 'non competitive' track events, but I didn't confirm this detail when I switched.
Word to the wise:
More insurance policies are excluding any motorsport activity, check your policy before participating. Special track insurance is available but is extremely expensive. (I saw a quote of $700/day!)
