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

Thank you for the reply. I assumed that they would do this as well, but when I talked to the collision center adjuster, she told me that they are going to repair it. Which leads me to believe 2 things- 1. The damage was not as extensive as I thought (but the rear bumper had collapsed on the wheel and I couldn’t drive it even to pull it off the road) or 2. My car is not worth as much as I thought (I am not so sure about this since Prius is still a well selling car and I had purchased it from a dealer less than 10 months ago and the car was in excellent condition due to all the servicing being done at the dealership regularly).
It could be neither, but I am not well versed in this stuff.The question is, if I decide to get it repaired and make the requisite payments on it, I would have a car that in theory I paid well over $15000 for, but in actuality is worth anywhere from $6000 to 12,000 (75-25% loss of value). Should I press for "total loss evaluation?
