Sorry to hear about your loss. It's worth contacting the Ford Classic & Capri Owners' Club (www.fccoc.org.uk/) as they might know of an enthusiast looking to take on this sort of project. It's really hard to put a price on this sort of project - a complete car that had failed an MoT would be worth about grand. A collection of boxes would be worth less - and unless he kept detailed notes and pictures it would be hard to know if the car was complete. How far did he get with the project? The value will be higher if he's done all the welding or rebuilt the engine, for example.
