Possibly the only 2018 S6 with the V8 for sale in the UK. Very well maintained with a service in April 2025, new MoT and an Audi main dealer health check (video available by email). No scuffs on the alloys, good tread depth on each tyre. Cream interior. 2 owners from new, myself for 5 years, and kept under-cover. Fitted with Ghost immobiliser
