The trunk lids is ok for the price as the trunk lid is "just" $880 which is cheap compared to others.

This is an excellent example of carbon as black aluminum. There are great applications for carbon but in sheets like this aren't good unless they are using honeycomb core the savings will be minimal.
Additionally, carbon pieces like a hood are often sized for handling loads and durability which can further reduce its weight savings opportunity.
