seeing as everyone who owns one has been on this thread at some point I thought I'd post up hear. Considering the rs6 (avant) in the near-ish future and trying to get some background. I'll be looking at 30-60k miles ones either 2003 or 2004. What are servicing costs like? What should I look for? Do you feel you can use the power with a baby in the car or will you always be backing off?
