Nice Turbo break down shot! That's one job I have not done yet myself. Your making really nice process with this wagon, would like to see more pictures of course, can never have too many. I find these cars addicting. They are fun to work on and drive. Hopefully you get the point where your doing the later most! I drive mine about 20K a year and after 5 years still find it to be one of the most enjoyable cars I have ever owned even with it's quirks. The way your going this car is going to see another 30 years on the roads. As to your sagging rear, before you spend a lot of time etc, go ahead and get those rear subframe bushing replaced, they make a lot of difference. 123-350-03-75
1 SUBFRAME MOUNT KIT (Wagon subframe kit, Mercedes) The price is a little shocking, but you will be happy you did it. Mine drove like a different car after. Getting them in is a little tricky so search here for the instructions and read them a few times.

The difference you made with your interior carpet...wow. it's inspired me to do the same. what was the recoloring product you used?
