w202 and rust

[BMWChris]

Hi, am thinking of buying a C36 or 43 and my research keeps throwing up "rust" but I can't get specific information. Is this rust as in "bubbles round the wheel arch" or rust as in "you'll need new sills" like some kind of MGB?

Appologies if this is covered else where - the search function seems to be playing up.

The rust talked about is like scabing round the boot lock, rust under the window seals, scabing along the wheel arches etc. They can be problematical to remove but doable.

Thanks, so it should be pretty easy to spot. Why do they do it? Can you eradicate it permanently?
