Some inspiration

Hmm, I started off using unwrap, but I found it was easier to select a subset of the faces, and then use the "Project from View" method of UV mapping. That way you can go above the car, select the faces that mostly face the top, and then map them; look at the side of the car, select the faces that face in that direction, and map them; etc. Afterwards you can position the different sides in a way that is sort of like unwrapping them.

The trouble I had with unwrapping was that certain faces would be scaled differently than others, making textures get applied in an inconsistent manner. So for instance if I wanted a pinstripe that went down the side of the car, it would be thicker in certain parts and thinner in others. Thus I switched to projection because it kept things proportional to how they really were. Take a look at the XS texture (and the UV mapping in the .blend fine as well if you like) for an example of what I mean.

that sounds like it will help allot. thanks.
