appears that last night someone stole my passanger wingmirror glass and backing!
well after a phone call to BMW I was quoted £77! following a quick browse online I found it for £35.25 including delivery (Sure it's after market but its indentical in looks!)
I called an a local BMW specialist who advised me "its too good to be true at that price" and still awaiting for him to call me back.
I honestly don't think you'll find it any cheaper than this, e46 Coupe is my car and astounded at the price!
(I don't work for them or related in any way just thought I'd share the knowledge!)
