Well, I'm not sure if this is news to anyone or not, but Ford
apparently releases a bunch of product shots as CC-BY.

Ford don't describe their photos very well, and Wikipedia doesn't have
an article on "car frame" so I don't know what this actually is, but I
feel pretty confident it could be quite a valuable illustration. :)
Best that car nuts pick this one up...
