Considering the complexity of the surfaces on a car body, I doubt that any of the free packages would do what you are looking to accomplish. Look at a package that is good at working with surfaces. Some cad programs work with solids better than surfaces and vice versa. I use VX, now ZW, which was developed here in the states as a proprietary cad/cam software for Samsung, then subsequently sold to the Chinese. However, development was kept in Florida. You can download various versions for a free 30 day trial and there used to be lots of tutorials available so you could learn it on your own. We do full 3d cad design including complex blended surfaces, so the software is at least as capable as I am. E-mail me if you have questions
