2001 AUDI S4, 67K mi, Cold Weather pkg, every option except nav, GIAC chip, APR catback, Eibach springs, short throw shifter, 325hp-29mpg, under NADA, $19,900, He is asking the $19,900 and I offered him $18K is that a fair price or should I go lower? I am 80% sure he will sell for $18K

 

18k is a pretty good price for a car that year/milage/mods
