Reassuring points
Reliability- The `5.0 TFSI V10 BUH` gives the `RS6 Avant C6` a completely abnormal character for an estate.
- `quattro` genuinely helps put down an amount of power that very few family cars of the time could handle.
- The Avant format adds real practicality to what is otherwise a wildly excessive technical package.
- A very well maintained example still delivers rare mechanical force and emotional presence today.
