I own a 2002 S6 Avant. Considering putting it up for sale.

Black - Bone stock 25,000 miles - I bought it new
Black leather w/ alcantera seat panels & trim
Tiptronic w/ paddle shifters - Symphony Bose stereo
New Bridgestone Potenza RE050A Pole Position tires 255/40/ZR17
1 set Blizzaks 235's
1 set Audi Winter Mats, car has Audi mud flaps
Never in an accident, garaged history w/ cover.
This car has been coveted.

Any suggestions on what price to ask?
