Well, it seems as if a lot of folks are focusing on the ergonomics, which I think are pretty good. Given that these cars don't handle that well, I don't find the seat design to be much of a drawback.

What I don't like is:

1) Sweat-inducing vinyl. Yeah, yeah -- it's the vaunted MB-Tex, but tell my legs that when it's 100F in the shade and 90% humidity.

2) Funky Pinkamino, Pooamino, Bronzamino, and Amberamino, descendents of Palomino.

3) Over-boosted steering.

4) Non-adjustable steering wheel position.

5) Vacuum everything, with the attendant feature of having lots of other stuff go haywire when one little thing leaks. The extra feature where much of the system can be contaminated with engine oil if the shutoff diaphragm fails is pretty nice too!

6) Seemingly-neat fiber optics for the upper console switches, the ends of which aren't integrated into the electrical connector, so you need three hands to get and keep them in there when reconnecting the switches.

7) Upper console jammed full of switches, vacuum lines, fiber optic lines, and wiring. This feature ensures that working on one thing will negatively affect something else.

8) A front sway bar that's a structural member for the suspension.

9) Doors which depend on little plastic pieces for them to shut right, said plastic pieces being unavailable separately from the whole striker.

10) An HVAC drain made of open-cell foam. The misalignment issues and bacteria harboring are great, and lack of accessibility makes this even better!

11) Cascading hood/engine compartment drains that will fail to work properly if one bottleneck fails.

12) A welded-together front valance that requires "real" bodywork to replace.

13) Springs that require a special tool to compress.

14) A long and convoluted valve cover which has only four bolts, no flange on it, and seals against a hard gasket. It's great how the u-shaped gasket faces upwards, so it catches the oil dripping down and helps to channel it to the outside of the valve cover. It's even better that the sealing rail is only a couple of mm above the base level of the head, so the gasket is always bathed in oil.

15) Bullet fuses (I hate this feature of my '80s BMWs too).

16) Hard-to-find o-rings used all over the place.

17) Front bearing caps that let grease seep out and crud up the center cap area of the wheel -- attractive!

18) Backup lights in the perfect location to get busted off if your wagon's bumper scrapes against a driveway entry.

19) Slooooooooow! At least I'm getting 29 MPG.

I could go on, but I need to go out and fix some vacuum-related issues...

1) I really don't like the later climate control system, where the two setting for air are hi, low, and whatever the car feels like.

2) Could use a bit more noise damping, a la 126

3) Don't like the seat adjustment, esp for higher or lower. It's sort of a clever design, but a little cumbersome in practice.

1) Ashtrays are full. All four of them. Again. Just had it fixed a couple of weeks ago.
