To recap: this car had the
OBC replaced in 2018
LDU & Gateway module replaced in 2020, and it
won the "most coolant found in an LDU" award in May.
Without a repairable LDU, its value is in parts. The JdeMO undoubtedly has value to someone. Have you received a quote to buy it, from QCC? They could get the most use from parts; most of use end-users can't afford to store an entire vehicle for a future part need.
The major parts that have value are the LDU (yours has not even core value, probably
), the HV battery, maybe the OBC (though that's maybe $250 for someone who needs one, as Model S ones will work in most cases). DC-DC has a little value, but again they're exactly the same as the Model S and readily available elsewhere. The heater, esp. if it has been replaced, is worth a few hundred to the right person (the original ones tended to eat their fuse, located inside the DC-DC converter, whose cover is glued-in-place
). The Gateway, but they don't have a large failure rate. Ditto the thermal controller.
Misc stuff like the battery heater and the four coolant pumps have some value, again for the right person, as they're not all that expensive new, but still . . .
Now, if the LDU was repairable, someone might take it on as a challenge. But soaked? It can be impossible to restore the stator's HV isolation resistance, and finding good replacement inverter parts is not a lot of fun, either. All-in-all, not something I'd care to do.
Is it currently located at QCC, or Santa Ana?
