Is the box damaged? It's reinforced inside with a compartment for each car, each car is on a base and each car wrapped in two layers of bubblewrap...how did they get damaged?

There was no sign that the box had been crushed in any way, but perhaps it had been dropped and the cars with the rigid wings struts were more vulnerable. I notice that your BMW V12 has a wing that has some free movement. But with the other 2 cars you could see the wings detached within the bubble wrap before unwrapping them.
