I did that. Drove into the rear bumper of a pickup truck. They stopped estimating at $26k and totaled the car. Now granted I was dealing with a high end repair shop and living in a high cost area and paying to have the work done. The first thing you need to do is deal with the frame and any such issues.
After my accident, I mentally estimated $3k. But you could see where the doors had been driven back against the rear body structure by the chipped paint. Which means the frame flexed and the future crashworthiness of the car was compromised. And, BTW, my airbags didn't deploy.
They put the car on a laser frame alignment machine and had values for the car and the car was bent. So a new front clip would have had to be put on or the frame straightened. Some parts, once deformed, don't have the same cushioning effect in the next crash
Mine looked like your picture.
