If each car averaged $50,000 value (its probably higher) - that’s a $200,000,000 cargo at the bottom of the ocean!
I saw one report that the whole cargo claim would be $438 million.
Starting price on almost any of these except some VWs would be $100K plus. Some 2x - 4x that much.
Likely no Seats or Skodas. Other VW brands include Porsche, Bentley, Lamborghini, Ducati (probably none of those, either), Audi, and, of course, VW. (They also mention Cupra, but the link to that page appears dead, and I’ve never run across one).
From the pictures provided during the attempts to save the ship most of the cars were burned. A burned car has no value, just the liability associated with getting rid of the hazardous waste remaining.
Even the parts from the cars are useless after an intense fire.
