I just took a look at both models, and they look great, but need a little clean-up. There are parts of both models where the faces are not the same (highly visible in the boot). This can be easily corrected in whatever program you used to model them, just make sure all the faces of the model are aligned. When this happens in pepakura, there is no way to fix it, and it makes unfolding the model impossible from a practical standpoint. Depending on what program you used to model these, I'm sure there are those who would be more than willing to lend a hand, myself included.
