Looks too nice to be a parts car. The pictures are not very big so I can't see rust, but the early alloy wheels are probably worth $400 or more if they are not bent, curbed, and can be refinished. Depending on where you are in the country, a "driver" class car like this in decent shape could bring $3,000 +/- By the time you replace brakes, fluids, tuneup, carb adjustments, you might have another $500 into it. Buy it and please don't part it out.
