I have a 1995 E420. The center console (with the sliding wood cover) works great to hold drinks. I put a 16 oz. coffee cup in there every morning, and it never spills. I modified the sliding cover to be a bit harder to move back and forth, so that it doesn't open suddenly and let the drink spill.

Works great with fast-food soda cups, and 20 oz. soda bottles too.

I'd like to try the under-the-armrest holder, but i don't want to drill holes in my car anywhere. So for now, the console works fine.
