I don't suppose they can salvage the cars?
Well, the boat sunk, so no. But even without sinking and having fire damage, the answer for legal reasons is no.
Back in the 2000s a Mazda ship stayed tilted for weeks, because the ship got out of balance, but there was very little damage to the cars. Mazda still decided to scrap all the cars, because of insurance reasons. Fluids not reaching certain parts for extended time can cause later problems, etc. They had to blow all the airbags out I think in Oregon, one state where there was no environmental law against it. 2 guys in gas mask went from car to car and blew 20K+ airbags for weeks.
