Looks like the inner wings have been repaired at some point with rust coming through again. not a cheap job to do properly if both need to be done.

Also judging by the rest of the bodywork, I would look very carefully to see the condition of the bulkhead before committing - need a good light and look through the slat/louvres type things under the front windscreen - if bulkhead full of grot, walk away as its ££££. Ask me how I know!
