Hi Pat:

I too was surprised.  I don't think that this amount of wear would be
typical for a maintained Audi with 78k mi. on it.  When Detlev and I saw
that the engine and accessories looked "well used" I agreed that a rebuild
made sense.  It made me wonder how many miles were actually on the engine
or if the car had received poor maintenance.  I guess the other possibility
would be that it had many very short in town trips or other "severe
service" use.  I have heard only good things about how Audi motors hold up.
This experience would bias me towards using a donor car rather than hoping
donor parts from a wrecker would be as hoped.  I think there was a thread
on this 4-6 mos ago and the conclusion was that whether or not to rebuild
remains an individual decision.

Best regards,
