Does anyone have any idea if the IS or GS models with auto folding mirrors would fit on the 2014 CT? I wish these would have came standard with the CT.

 

Ive had multiple 2IS, no US models came with them. I believe the EU models did have an auto-power fold option, there was a pair in the 2IS classifieds quite a while back. IIRC they can be wired up but you would need to tap into the door lock wiring. As far as being able to interchange model's mirrors, I believe the newer generations models all share the same dimensions for mounting points.
