That's substantially less than I would have expected. It means each car was valued at ~$20,000. I would have expected the ship itself to cost ~$250,000,000, but the HMM Algeciras, the biggest container ship in the world, only cost $140,000,000 to build. https://www.shippingandfreightresource.com/hmm-algeciras-lar...

Merchant ships are actually pretty cheap. If you think about it, it's mostly steel supporting empty space and a really big engine.

It's not at all unusual for the cargo to cost far more than the ship that's carrying it.
