Audi RS6 Avant (C8)
Why 7.5: Half the buyers are wagon romantics who cross-shopped nothing; the other half wanted a Urus with less attention. The ownership data splits right down that line.

Sound
The 4.0 TFSI has a deep, hard-edged bass that suits the car, and the sports exhaust cracks on a closed throttle. But it is the quietest of the German super-wagons by design, with turbos in the vee, a particulate filter and a mild-hybrid system all working against it.

Front ISOFIX is a cost option on the A6/RS6, not standard — Euro NCAP's table marks it available but not fitted to the test car.

The long version
Order one and you are either a wagon purist who never considered the SUV at all, or someone who wanted Urus-adjacent presence without the valet-line reputation, and the used market does not really distinguish between the two once the car is a few years old. Values have slid in a consistent, unremarkable line since 2020, the kind of depreciation that suggests most buyers are actually driving it rather than protecting it. Daily Driven fits the mileage data even if the badge-shopping half of the buyer pool keeps involvement from climbing higher. The argument for owning one is split; how it gets used mostly is not.
