I worked on this car a little last night, and some today. I've basically finished, although I suffered a setback when my power went out. I hadn't saved the headligts, nor was i completely finished but that was about it. The only object on here worth anything is the one named Car (self explanatory). Here's a pic:
I made it through the line tool, and then extruded it, though the caps didn't quit work so I used the same process to create the sides. Nothing I did would correctly smooth the edges, so the edges are very sharp.
Overall, I'd have to say that I'm pretty plead for a few hours work on my first object that's more than a 3D "doodle."
