You are essentially selling a project plane. While I agree it most likely is worth more than 5k both as a project or parts, time is not on your side. You may find a dreamer who has a vision of completing the project and willing to pay top price. To estimate the market value, start by finding a similarly equipped flying 12 and start subtracting things. First of all, the engine is really not in the mix due to its unkown condition and undesirability(low hp). If it needs to be recovered, estimate the cost of materials plus the labor to recover(shop rate x hours). What does it need to make it a Super 12? Does it have 18 gear and tail? Which STCs and/or field approvals does it have? Do the airframe logs have the paperwork that goes with the mods? Was the work your Dad did under the supervision of an A&P? After all the moves, are all of the parts there? There is a lot to consider when buying a project. A knowledgeable buyer will come to the table with a sharp pencil. There are many places to advertise the plane e.g. Barnstormers and Trade a plane to name a couple. They both have a web presence. Cubcrafters in Yakima may be able to point you in a direction. They manufacture and rebuild cubs. Good luck with the sale.
