My wing mirror glass flew off on the m-way so I posted a thread ( http://www.z4-forum.com/forum/viewtopic.php?f=3&t=76278 ) thinking surely this is a one-off, in the meantime I got a quote from local BMW dealer: £96 for the part. Within hours got lots of very useful info from the thread and links to online shops selling just the mirror glass with adhesive backing – bought one for £16 arrived 3 days later - glued it on sorted! Thanks guys (donation to the forum just sent
)
