Let me play devils advocate. Without a least a verified inspection of the car, original owner photos, some kind of original paperwork etc the car will be considered a COPO "clone" which will only bring about a 3rd of what the car would be worth as a verified COPO. The car looks like it needs tons of metal work. If it does get verified you would want to us as much GM sheet metal as humanly possible which is probably around $12 to 15k to purchase. Then there's the special parts like the BE rear end which is about 12k. For a un-documented car you can see how upside down you get really fast. I hope this works out in your favor. You don't see a whole lot of black COPO cars.
