NAC: BMW List/Parts Help?

[Alex Kowalski]

Hi, I realize this is not Audi-related, and may be anathema because it's
about a WMB, but:

A friend of mine just purchased an older (1993) BMW 525i and needs some help
with maintenance, spare parts, and supplies.
Can anyone here at Audifans recommend some good parts suppliers (used and
new) and perhaps some internet resources similar to
the Q-list?

Many, many thanks in advance.  Now back to your scheduled Audifans....my
apologies.
