Your situation is a bit different in that W212 wagons are pretty rare and even rarer at auctions. Therefore, there probably isn't much of a Manheim database on them due to scarcity. Consider that even on ebay there are currently (as of a few minutes ago) only three such wagons and all three are 2011s.
People just don't seem to let their MB wagons go, which causes rather lopsided (or, as you put it, outrageous) values, simply because the supply isn't there while the demand usually is. A case in point are nearly 30-year-old W123 wagons that with low miles can clear nearly $20K.
Sorry I couldn't be of more help.
