I've got a sliding cover. 57-plate.
It's a bit too shallow for my liking. Keep getting paranoid about red bull spilling everywhere, which is why I've switched to Lucozade Active. It has a lid.
The best cup holder I ever saw was in a Saab at a motorshow back in the early 90s. The action was sooo smooth, even to this day I haven't seen a cup-holder that works that smoothly.
