Raise the ship, take the cars to the scrappers in Missouri! Instead of scrapping them, they will clean them, straighten dents, get them running. Then slip them down into Arkansas where they can be sold through the Auto Auctions without titles.
And for $45 they can get a good clean Arkansas title showing the autos have never been wrecked or flooded, and ONLY driven to Church on Sundays by the car dealer’s grandma.
Based on pics I’ve seen of battery fires, there may not be much usable stuff to rehab there.
