As of now the only replacement part is the hood; the other body parts can supposedly be repaired. The estimate didn't include the carbon fiber top which I'm sure has to be replace as well.
It will probably go up to $10,000-12,000 when its all done.
I spoke with Trade Secret but they have a really long wait.
