Audi A6 review

Pros

Incredibly quiet and refined, making it a perfect motorway cruiser
Stunning, high-tech interior that feels genuinely special
Strong and efficient diesel engines are great all-rounders

Cons

Rivals like the BMW 5 Series are more fun to drive
The ride can be a bit firm on sporty S line models
The long options list can make used models vary hugely in spec
