I think it's worth it, your own shipping container will keep the car safe.
Shipping something like this, you need a good shipping container. I have shipped things a few times, and the first time something happened, but all my stuff was ruined... No one could explain to me what happened, and I was furious. Now when I have to ship something it's done only with containers from https://www.tigercontainers.com/contact-us/shipping-containers-melbourne/. The problem might not have been in the container the first time, but I am extra cautious. When something like that happens, you get the insurance money, but some things are priceless for some people, and I would be furious to lose something like that again...
