2016 Eco Two - Totaled?

I tapped a deer, very light front end damage but it caused every airbag to deploy.
160k miles, immaculately maintained - I have every reason to believe it has another 100k+ miles left in it.
Car is paid off, but insurance is liability only.

What Would You Do? Suggestions?

 

To what degree would you fix it? What is the max amount of $ would you put into repairs in order to take advantage of the remaining 100k of usability?

 

Heat exchanger has not been replaced - I assume this must be a rather expensive item that I should expect to be replacing soon?

Im also wondering what the community thinks of the airbag replacement process... Are these incredibly difficult to swap out? I do have a friend that is ACE certified and willing to help, but he deals primarily in regular mechanical/maintenence issues, not necessarily total vehicle repair.

Is it possible/smart to just run it without airbags?

What are the main issues, other than heat exchanger, that I should be asking myself prior to making this decision?

Any and all help is appreciated... This insurance debacle has me in pretty dire straights at the moment.

 

Interesting approach, but I would imagine the donation value to be unable to offset the financial burden of replacement, even if replacement only involved a few thousand.
