Basically, your mate is looking at the start of a build not the end.
There are a lot of kits in this condition out there - people started building, it took longer than they anticipated, the rules changed, some of parts they've got wont be allowed any more - the wherewithall is not there to re-do and complete.
His position is now similar to someone just acquiring a kit from a supplier - has some useful parts, some can be made to work - others not.
Probably not what he signed up for.
Frankston Victoria? (only Frankston I know of) Before he gets too despondant call Enkelman's and arrange an appointment to see if the project can be salvaged
