I'm a lurker here looking to get into a B6 S4 Avant for a long time now. I found one with only 39k miles on it in the exact color combo I've wanted. Interior and exterior look mint. Automatic, no accidents, etc. What would you say is a fair offer price on this car? I'll post up the classified if need be, but rather keep it off due to possible competing bidders. Is the timing chain still a concern with only 39k miles on a 2005?
