Deren, a flatbed is useful where your located of course for ranches etc., but being a 2WD, it’ll be a harder sell.
If you get it running and driving good, list it for $4500 or $5000 and explain the situation the family is in.
This is of course my opinion, then drop accordingly if no interest.
I’m selling my son’s 1999 BMW 540i, no interest at all, but bad time of the year to sell it.
