 Bought my A6 quattro wagon new in RI. 
Used if for commuting and carpooling and
it it also got complements for its looks
and ride.  Never had a problem in bad
weather with the car.  Moved to SanDeigo
and I put 18" performance tires on the
car and handles like a 5 series.  Plan
on lowering it an inch as well.  Best
purchase I could have made I have the
versitility of an SUV but the comfort of
a luxury sedan and the sportness of a
sport sedan.  Can't wait to purchase my
next audi quattro wagon.
