As above, worst case you've got 13 years of accumulated crap under them and they crumble in your hands like my MK1 did! Then you go out and buy some new wings with oval stlye repeaters and get the rear patched up, jobs a good un! Just to say though, my white one is an M reg and one of the arches was a bit scabby underneath and rust is like icebergs, there's always loads mor under the surface.
