Cost of rusty project or parts car

Cool fixer upper. Stock repaint and some baby moons with beauty rings. Or leave the "patina" after giving it a wash. Heck everybody loves the beat to **** look nowadays. Tune up the six and cruise it. Do a lowball at $500. I wouldent part it, i would do a little fixin, drive it a bit with for sale signs in it, and flip it.
