Thanks Bar,
The intention was to swap all the best bits on to the blue one (doors and a bit of trim), apply for the log book and sell on as a project with V5 to make a few quid towards spraying the blue one. Unfortunately it's not straight forward as I think it's been built out of scrap parts and has an unrelated reg plate, so no simple way to get a V5.
It's not impossible but just not for me at the moment. Best to let someone else have a go or break for spares.
It's on gumtree just now and has a fair bit of interest.
