Does anyone know if any manufacturers make trim to go around the door handle/lock button panel (indicated in red in the pic)? If not, what would be the best way of making it myself?

Try Putco

I know they have several trim pieces for S197s and they even have a half mirror chrome cover like Midwest Auto Gear has the colored ones. I don't know if their site is updated fully, but check them out and call if you want something other than what is shown.

 

If you aren't wanting a polished look you could always paint them like people do the window plates.

 

I'm not seeing anything on putco's website for interior accessories except for pedals

 

Id take it off and paint it, either to match your exterior paint, or your dash panel.
