Reassuring points
Reliability- The supercharged `3.0 TFSI EA837` delivers a broad, easy character and makes more day-to-day sense than the old coupe's `V8`.
- The `7-speed S tronic` and `quattro` make for a very fast and very easy car when maintenance has genuinely kept up.
- The `S5 Cabriolet 8T` remains a proper usable four-seat convertible with a cabin that still feels solid today.
- A car already sorted on cooling, gearbox and roof work can be far calmer to own than it first appears.
