The strip which hides the cupholder (horizontal, not vertical) is above the glovebox, is called the "dash trim strip", and is NOT affected by the painted slats.

All of the trim surrounding the air vents themselves is in leather instead of aluminum-look, if you get painted slats.

You can order the dash trim strip in leather separately if you want (which I did - option CVP). Otherwise, it will be in aluminum-look.

There is another option called Leather Package Switch Panel (EAA), which will give you the air vent surround, trim strip, and some additional leather, but it's more expensive, on the order of $2000usd.

Hope this helps
