Buying a V8

[Steve Ensch]

I have been looking for a V8 Quattro.  I have noticed on these cars that
they remain very tight still above 100K miles.  I have noticed some problems
with oil leaks off the back of the engines, exhaust leaks, and soft brakes.
Is there a site or someone with a list of items to check on these cars and
which ones to steer clear of.  Are the 1990, 3.6l models vs. the later
models, which one is preferred.

Thanks

Steve
