Crashed. Buy it back salvaged or not?

Well. I now have the coveted COMPACT EDITION 2010 Prius. It's 6 inches shorter on the right side after spinning out on the highway and crashing butt-first into the concrete wall of a bridge. Better than flying

I'm looking for advice should I buy back my car from insurance company on a salvaged title or not. Or better stated, "What should I be willing to pay to buy my salvaged title back from ins co?"

The insurance claim is in process, and a couple mechanics so far told me to expect it gets totaled because of the amount of crunch that went on at the point of impact, and the ominous airbag light.

WHAT BROKE
The back hatch and read passengerside door no longer close 'right' though they do latch shut. Rear cargo panel no longer fits flush. Broken bottom of rear right tail light. Rear right bumper support is flattened to nonexistant. Rear subfloor of hatchback area is crunched in. Seatbelt pretensioners discharged, or SOMETHING is causing airbag light anyway. Passenger door arm rest pushed in.

WHAT'S FINE:
NO broken glass. No battery problems. All electronics and lights work normally. Engine is fine. Original traction battery still working fine. Tires in great condition and undamaged. Spare tire never been used. NO ODB2 codes reading on odblink LX with torque pro. (airbag light makes me doubt the ldblink though, but it indicates engine RPMs properly so it's communicating with something alright) Dealership verified alignment was fine in back. Car drives straight without dragging. Airbags were not deployed. Recent new oil, headlights, wipers. Never leaked a drop of oil.

I like my car, and am reluctant to change. Especially reluctant to spend a lot right now. I was getting ready to upgrade the nav unit until this happened.

But I also kind of want something I can plug in at home though to offset the gas I have to purchase, and visit gas stations less. There is some rust underneath, and I can't help but fear that traction battery is gonna fail any day now as old as it is without replacement. Though I was looking forward to upgrading it from NiMH to LiPo when the time came.

I'm fairly sure they're gonna total it. The two estimates I got came in in the $5800's. And kbb was showing $6400-$8300. I've got a $1000 deductible, so they'd spend less to cut me a check I think than to fix it.

...b...b...b..But it still runs.... and I don't want to have to move all my stuff to a new car if I don't have to...

So. If they let me buy it salvaged from them for a dollar, I'd take it. If they want $5000, I'd walk. but where to draw that line? They should negotiate some right?

It has next to no resale value at this point, but I could probably keep it for a year and sell parts off it bit by bit to save up for my next ride. I don't feel particularly unsafe given that there's at least a couple more feet between that back bumper and the back seats, which are seldom occupied.
