Interior mods

Just wondered if anyone has any good ideas about interior modifications on an 04 cavalier.

On my 1993 I just completed a two tone job in black and hot pink, I painted everything, changed the shifter knob, added peddle covers, re did the headliner, got a nice matching seat cover set. I'm not sure if there is much else to do when it comes to interior mods, I still plan to change the carpet and install some interior under the dash lights.
