I would go with polishing and a good coating on the lenses. Does anyone sell the 3M clear bra material for the CTS? I would imagine they have it and that would add some protection once you get the finish where you want it.

May want to try one of the simple Meguiars kits before you grab the sandpaper. I was pretty pleased how my wifes headlights came out on her Lexus with using the simple kit.
