Our recommendations
Which used Audi A6 estate should I buy?
The 2.0 TDI four-cylinder diesel is an engine that imbues the A6 Avant with remarkable refinement, such that there are times you wouldn’t know it was a diesel. It’s the cheapest in the range and is also the most economical and, unless you are more interested in straight-line speed, that’s enough to make it the one we’d seek out.
Likewise, we’d stick with Sport trim as this offers all the goodies you could reasonably want or need.
