This is another attempt but a little different. In this case, the car design is from scratch with no known real world counterpart. The wireframe being made point by point and constructed mainly in Anim8or. It's slow and tedious, but if it turns out good... This picture shows two different renderings as it went along. The top one is nowhere near complete, but I was goofing around seeing how it would look with wheels under it.
