The rear end is sagging -- this is caused by several things. You probably need new links in the rear suspension, along with new bushings for the spring link, too. Might as well get subframe bushings at the same time, they are dead if the links are.
Spring pads shrink or crack and fall out, again this lowers the rear end, causing the excessive camber. So does sagging springs, but you can only really measure those out of the car. I would start with replacement links (no, you cannot replace the bushings, they are vulcanized in place, and are part of the spring system). The rubber goes bad, showing up as shredded bushings, or just as an out of center bolt. All those bushings contribute to spring action, so when they go bad the car sits a bit lower, hence more camber. New links require a set of new bolts, as they are actually a new design from the W210, and have 210 part numbers. Jack the rear, leave the suspension hang, then unbolt the links in turn and replace with new ones. Leave the bolts loose enough for the inner sleeve to move freely on the bolts, then jack the wheel carrier up to level and tighten properly. If you tighten them with the wheel hanging, the back of the car will be jacked up quite a bit and handle very strangely, as you will then have excessive positive camber. The bushings in the spring link, one on each end, press in and out -- wear on either end (and one is rubber) will result in the wheel carrier moving outward at the bottom. This a the May/June project on the "new" 300D -- had all but the subframe bushings done on the old one when it was wrecked.
