Here is my suggestion, a 1936 Cord, one of the "swoopiest" automobiles ever. AND, I know how to achieve the complex curves in paper as long as you design it in either 1/25th scale or larger. Among car modelers, 1/16 scale is also quite acceptable. Of course, the larger the scale, the more detail you can put in.

You design it, or something that looks like it, and I'll show ya'll how to build it.

I can get more reference photos, too.
