Tom, it sounds like it is definitely worth looking at. 7000 miles on a 2 year old car is pretty damn good. I have had this S4 I have now since late 2004 and it has been fantastic and it has 62k miles. No issues at all except tires and a small oil leak on the valve cover they repaired for free. I know an S4 is not an RS4, but I have read no threads anywhere talking about engine or tranny issues with the RS4 that are in any way common. Electrical is rock solid, its only the DRC. I am getting my new RS4 in 10 days, and I gotta say I am doing it knowing I will replace the DRC in a year or two, however long it takes to fail.

Is this in portland? I am over in Richland, but just moved from Portland. You know the climate, cool and wet, but I am sure he kept it garaged and again 7k miles, wow, nice. $50k seems OK, bet you can get it for $47k or $48k with a bit of haggling. But like you said, they are going higher elsewhere for more miles. However those are usually dealers. Bet if he tried to trade he would get $42k max on trade. So work that angle if possible.

Wait till you see the custom plates I am ordering, it will make you all laugh!
