Used Audi A6 Avant 1997 - 2005 review
Advice for buyers
What should I look for in a used Audi A6 estate?
The Audi A6 Avant has a well-earned reputation for reliability. It's solidly screwed together using proven, good-quality parts and the engines will run and run without a problem if serviced properly. So that's the first thing to look for: a full service history.
However, pay particular attention to the suspension. This is the area that gives most trouble, according to data from independent warranty providers Warranty Direct.
