Updated taillights on an 04 211
About the mirrors I don't know either, but again i put aftermarket on mine.
You need to look after the "line" of taillights!
Avantgarde to Avantgarde -> no issues!
Elegance/Classic to Avantgarde -> coding rear SAM, because Avantgarde has LED lights

Mirrors:
If you have a MY2002-2005 W211, you need to bore 3 new holes.
If you have a MY2006, it fits P&P, because this MY has both holes for old and new mirrors.
