I drove an '07 Century Classic for a while with almost the same looking crack and uncovered front. The mirror heater stopped working and the electrical controls started going haywire. Cover that front asap or you will end up having to replace wiring. The mirror assembly and front cover will set you back a few hundred and can easily be installed in an hour or two. Nothing sucks more than an iced up mirror.
This rig looks like something strait of the movie - Road Warriors - Mel Gibson.
Its wraith looking.
I have a cracked mirror which is why I found this just hoping I can glue in a new glass on the right power mirror.
They are pretty expensive to replace.
