I've found a couple of sources for Elise mirrors. Looks like it'll cost me around $375.00 in parts for the 3 pieces I need (front of the clamshell, back of the clamshell, and the mirror itself).
But, that's unpainted black.
So, I'd have to...
A) buy 2 mirrors in black, so they match
B) get the new mirror painted
C) buy the passenger mirror and a pair of the carbon fiber covers
Right now, I'm still waiting to see what Tesla has to say in the matter.
