I've been looking for a pair of heated powered and auto folding mirrors for my 2005 Impreza WRX wagon but I can't find any.

The best I found is heated and powered but no auto folding selling on ebay.

Do they exist at all?

Also, how difficult will it be to install them myself? Last time, I installed two Spec-D head lights and that took me a week to get the aim right.
