What's a '69 Z-28 or L78 project car really worth?

[Charley Lillard]

"Finally, I have a friend that has an original drivetrain Hugger Orange Z-28 with docs. He has owned it since 1989. Original paint, maybe 60,000 original miles. Engine is all there, except it has headers and manifolds/smog are long gone. Standard black interior with console/gauges and has cowl hood. He hasn't driven it in 3-4 years, but it runs and drives. He is willing to sell it also. What would be a fair price for this car? "

Sounds like too good of a car too restore. Get pics. The other two I would avoid. Be patient in your search.
