This 2023 Audi S6 Avant TDI V6 Black Edition is a well-maintained estate car that has been kept by only one owner from new. It has covered a very low mileage of 29,844 miles and comes with a full dealership service history, with the most recent service completed on 4 March 2026 at 25,648 miles. As a Euro 6 compliant vehicle, it is designed to meet modern emission standards while offering the reliability expected from a single-owner car with a complete manufacturer service record. The vehicle is powered by a 3.0L diesel engine paired with a four-wheel drive system, allowing it to accelerate from 0-62mph in 5.1 seconds. Practicality is a key strength, as the estate body style provides a large boot space for luggage and equipment. The driving experience is supported by the Tour Pack, which includes adaptive cruise control, and the Comfort and Sound Package, featuring keyless entry, a luxury branded sound system, and 360-degree parking assistance. Further convenience is provided by the rear-view camera, deluxe 4-zone automatic climate control, and light and rain sensors that automatically activate the headlights when needed.
