The steering wheel buttons on my '01 E320 wagon are sticky and nasty, upols. cleaner gets the gunk stuck to it off but they're still tacky and melty... The same goes for the top of the drivers door panel... And the rubber at the bottom of the windshield (outside) is all crumbly, just like the antenna on top.

I know the sun must shine in Germany, though maybe not as much as in FL, but this is a real pain. Do 'they all do that'? What's going on here? Do I just go Lexus next time, LOL?
