Reassuring points
Reliability- The `S4 Avant B7` offers a rare mix of true estate practicality and a high-character naturally aspirated `V8`.
- The `4.2 BBK` can remain very satisfying if the base car is healthy and the service history is serious.
- The `B7` phase often feels more mature in presentation and set-up than the earliest `B6` cars.
- A lightly modified car that has been properly brought up to standard still makes a real enthusiast family wagon today.
