I think I personally saved around $1k/year on supercharging
Based on what you have posted in this thread, it appears to me that you are basically asking:
"is there a way I can risk the 36k repair job being the actual cost of the repair and not being more, as well as figure out some way to keep supercharging on a salvage vehicle, to save 1k a year in charging costs for myself?"
You would have to keep the car, find someplace to repair it, hope that the 36k current quote didnt ballon up (body shop quotes always go up when they start taking panels off), and then find someone to re enable supercharging on your "now salvage" vehicle, and do all that to save 1k a year (which is less than $100 a month).
Thats basically what you are asking.
