I'm just picky. I think I may have screwed up the temp sensor myself. The AC is the biggest issue, which is a common MB gremlin. The Seat Heaters are known to fail regularly, The locks aren't a big deal. They seem to be working fine now. The pressure switch for the glove box light hangs up sometimes. None of these issues are dire or compromise my belief in the car itself. I think once these minor quibbles are worked out, all will be well with the world...
