That = amateur rust. The Sud was the definition of rotten, if I had the hindsight I would never had bothered with it. All that stuff is pretty minor, the only real strutural bit is the B pillar, the doors and guards aren't a major, but I'd get new steel welded in there myself.
For replacement bits and pieces (such as doors) you might wanna get hold of that Harry Landkroon guy, posts on Club K, posts on TS, and might even post here? He has E7 Corolla bits for Africa.
