...you could cover the hole with a bit of plastic ...

I have seen Sebrings with that plastic part removed. The cd changer Just is not visable. You have to get your head down below the window sill just to see the changer. The lack of the shelf/accessary plug component is not a tipoff.

A cover, like a glove box door would be easy. Attach the hinge to the bottom of the sled. (maybe?) If it was black It would look fine. No need to try and match the gray.
