good junkyards and 52K checkup

[Michael Hubenthal <mikehub@cisco.com>]

audi-philes,
i need a new drivers side seat for my '85 4kq. any ideas where to
find something like this? i've tried some local (san francisco bay 
area) junkyards but they didn't have the dark brown color i need.
any well known super audi junkyards out there? i've heard there are
a couple in the sacremento area but i don't know what they're called.

also, i need to bring my '92 100CS in for a 52k mile checkup. do i
need to go to a dealer for this? my regular mechanic says he knows
what that entails and can handle it. of course, he's motivated to
get my business. 

any thoughts on this would be appreciated.
thanks, spike
