What do you do with a close to totaled car?

2011 WK2 Grand Cherokee V8, 145,000 miles.

Trade offer was 5k a couple years ago when it was operational.

Just burned an alternator which fried main computer. Needs thermostat, brakes are completely worn. To fix all these, I was quoted roughly $3500 for everything minus the $650 I paid to fix the alternator before the fried computer was diagnosed. Mechanic stated there could be other electrical issues that can't be diagnosed until main computer is replaced. Vehicle is essentially totaled at this point.

What do I do at this point? It's at the mechanic, not drivable. I will have it towed somewhere but who if anyone do I contact to offload this? There has to be some value and the tires a nice, tranny has no issues, and engine runs well. Just kind of lost on where to go.
