[s-cars] Seeking advice on '94 S4 purchase

[Kevin Day]

Hello all,

This list seems like a great resource.  Hope you don't mind a few
questions from a prospective owner.

I'm going to look at a '94 S4 this weekend.  I don't know much about the
condition at this point, but it's got rather high mileage (~170K).
Other than the usual (records, t-belt, etc.) is there anything specific
that I should watch out for?

I understand that the turbo has an auxillary cooler that runs after the
car shuts down, which should be good for turbo life, but this might be
my first turbo and I'm a little wary.  If one had to be replaced, how
traumatic would the price tag be?  (I see that Porsche has some
applications for the same unit.  That's... not really all that
encouraging :)  Any (other?) high-ticket repairs that I should look out
for?

Anyway, any advice, pointers, etc. would be appreciated.  Thanks.
