Unless you're blind, Darkwood building pieces are a different set of models. If you think Darkwood rooftops for example, are the same as Wooden rooftops with a different colour pallete, I implore you to look again.

Thus, your analogy that the 'new car' is just the same car with a different colour is wrong. The better analogy is that Ford made a red Mustang GT350, then later, released a Mustang GT350R and painted it with orange racing stripes.
