How difficult is it to find a good 95 S6 wagon in the northeast??? About how much would one cost??

Depending on options/equipment/condition/mileage, they can run from $22,000 - $29,000....

I think they have a Silver 95.5 S6 Avant<ul><li><a href="http://www.autohaus-vt.com/">http://www.autohaus-vt.com/</a</li></ul>

these are super rare and super nice...
karquattro is a great source (my father purchased his there) also check out the quattro club classsified section (one sounds very clean in Denver). Be willing to travel for the right car... a $200-300 plane ticket is a small price to pay for the right car.
