S4 buying advice

[Jeff.McMeekin@Corp.Sun.COM (Jeff McMeekin - WWFO Training)]

OK, to hell with the 100S.  I'm going to go look at a '93 S4.  Fairly
high mileage (83k).  But I'm averaging 10k a year myself so
I think I can live with that.  I am having a mental
block spending near mid 20's for a car with that many miles
though.   My wife told me 'forget it'.  I told her '0-60 in 6 and a bit'
and she perked right up.

What should I be asking the current owner?  What can I expect in
maintenance headaches.  How long do the turbos last?
