Loss of value on a Prius after a rear end collision?

I notice that frequently after an accident the owner of the car suddenly becomes knowledgeable enough to declare that the car was previously “in excellent condition” I ask what qualifies you to make this conclusion?

I have no ide why you included your graduation, employment, or budgeting data in this post as it does not affect the process you should take (if any) to recover “loss of value”.
