Highlights

Overview

Every so often a manufacturer builds something gloriously unreasonable, and the C6 Audi RS6 is exactly that. It arrived with a twin-turbocharged 5.0-litre V10, 580bhp in standard tune and the pace to reach 62mph in 4.6 seconds while still swallowing 1,660 litres of luggage. It remains the only 10-cylinder RS6 Audi has built, quattro all-wheel drive putting the lot down without drama up to a limited 155mph.

This particular Avant, finished in metallic grey, takes that already generous recipe several steps further. It's a properly sorted, dyno-proven MRC Stage 2 car, its printout recording a hefty 726 PS and 1,067 Nm, backed by a considered list of quality named-brand modifications that are all documented in the history file. And here's the good news: none of it feels thrown together, the work reading like the wish list of someone who knew exactly what a fast Audi estate should be.

Cosmetically it's a lovely looking example, the paint glossy and consistent and the panel gaps even. It sits on a purposeful lowered stance that suits the car perfectly. Inside, the RS sports seats and carbon-look trim have aged gracefully, and the cabin still feels every bit the fast Audi flagship it was designed to be.

Reassuringly, it comes with a comprehensive documented service history and a full A4 folder of invoices to match. There's real everyday usability here too, the sort of car that will handle the daily commute one day and embarrass proper sports cars on a good road the next. This is a V10 super-estate that's been used, cherished and kept properly on the button, and it's ready to be driven and enjoyed exactly as intended.
