It is time now to start with the body shell panels; these are the visible parts of the car, those that sell your model and where you can't lie. In this particular case, the blueprints had a chronic lack of precision, so I decided to setup several cameras using the tumble, track, dolly, zoom and roll options. By watching image planes through different cameras, it gave me a far better approach to the real deal than just my blueprints. I modeled the body as a whole and then broke up the panels following the design. You can cut using the split polygon tool and then get rid of the triangles and ngons relatively easily. Working with even spaced topology gives you better reflections while rendering, and beveling all your edges keep the separations between panels perfectly clean.
