ive seen and proberbly repaired worse, it only sounds bad becuase of thw ay its written

probeberly a coupe of small holes here and there that just need cutting out and welding up, most garages acn do this, doesnt require a bodyshop, but make sure its a garage that you trust that will cut it out and not plate it up

you could get another shell and reshell it, or cut your losses, just depends how much you like the car and if you plan on keeping it that bit longer
