I may or may not have a car running in September; but I have a chassis for a 1/3 scale model! Pic can follow after I find my USB cable.

It's a control bar off a sailboard. Made of 1 1/4" aluminum tube; 80" long by 23" wide. max camber is somewhere about 35%. Fineness ratio is 3.65:1. Perfect for the model of my 21ft motorhome.

I took it into the office at the recyclers and asked for a price. They looked it over and said $10, and I took a Veteran's discount. When I got it home and took a bunch of paracord off, there was a $20 price on it nobody had seen. Score.

Two crossbars for axles. Two triangular scraps of ABS I already had are just big enough for bellypan material.

Edit: An example from a how-to page to help with the playing card analogy:
