as above, theres a guy by me who has one and i want it, its just a shell with doors its been in the weather for years and years with no windows uncovered

he said its got a new floor in it which looks right apart from the pond inside it lol and it is still solid i had a look myself, the bad parts that iv found is it needs a new scuttle panel, the petrol filler hole has rusted completly its just hanging in the back quarter and there rear wheel arches inside behind the panel has holes in both sides, theres a few rusty spots outside but nothing major,

what is this shell worth? he said he will let it go for the right price but i dont know what i should offer him, any ideas? i want a new project and this is the car i want

any advise would be great
