If you are talking mirror only then it should be around RM75 a piece, HOP. I replaced my EK civic mirror before and it's 1 year back. You won't find the mirror from auto accessaries shop but the place you should go is those auto spare parts shop, and you can order from some chop shop as well. For god's sake, just buy the new one to save up your effort and time to look around in chop shops and they won't sell you just the mirror which usually they will sell it together with the side mirror housing for 300 a pair.
It's fairly easy to install, but you can have accessaries shop instaledl for you if you are not confident.
