I'm doing a little research and was just trying to get a general estimate of the prices of the raw material required to build a moderate sized chassis of lets say of Factory Five Cobra dimensions. How much tubing is required and what is the general going rate per foot of the varius types of piping used?

I would also like a general idea of how much aluminum paneling would cost for the outer body of such a car (one I have in mind isn't convertible however) unpainted.

I'm guessing the materials for a good chassis could be had for around $1,500-$2,000 and consideribly less for body panels? Any estimates would be appreciated.
