It's described as a project, but from what I've read it just needs work on the engine to get it going. Looks like a B18 conversion too (1957 car would have been B16 and 6v from factory). Colours might not be to everyone's taste(!) but if it's a solid car underneath, paint is the least of the worries to sort out.
