Thanks for the tip Metro! Signed up for the group buy. This is not something I am willing to consider DIY for the time being. I spent a few 15 hour days in the garage with my E39 so I know what would be involved here.
I've been quoted (locally, by an indie BMW shop) $225.- MORE that what LTBMW is charging on the group buy. The SA I spoke to at the dealer I go to for my warranty stuff claimed they don't do it there.
