2006 Audi S4 B7 4.2 V8 Quattro Tiptronic Genuinely rust-free example of the last naturally aspirated S4. Imported from Japan in 2020, so no corrosion arches, sills and subframes clean. MOT to April 2027. Second UK owner. Drives faultlessly, no warning lights, no leaks. Timing chains quiet from cold and hot, no chain issues. Auxiliary belt replaced. Professionally ceramic coated April 2026. SPEC Recaro Alcantara sports seats, heated Memory driver's seat, reversing camera Cruise control, electric folding HISTORY 4 UK services 2020: 42,168 / 2024: 42,510 / 2025: 42,722 / 2026: 49,402 Dry-stored in a garage by the previous owner 2021-2023, hence the low mileage between services. Serviced by time as well as mileage, so the oil has never sat in the engine. Only 3,398 miles since the last service. Full carbon clean March 2026. UPGRADES quality parts, fitted by specialists Stage 1 ECU & TCU by Jackal Motorsports Jackal Motorsports intake Milltek exhaust BC Racing BR coilovers H&R anti-roll bars EBC discs with EBC Redstuff pads Stainless braided brake lines Brand new Rotiform 19" wheels Brand new Yokohama Advan Sport 255/30/19 Estimated around 370bhp with the software, intake and exhaust working together, up from 339bhp standard. The Jackal software comes with the car and the stock map is retained, so it can go back to factory at any time if you'd prefer. HONEST FAULTS Headlining sagging slightly around the interior lights Rear parking sensors intermittent 2025 MOT shows 42,647 miles; correct figure was 42,674. Tester transposed two digits. Service records either side confirm it. Everything else works as it should. Taxed on engine size rather than emissions as an import, so road tax is roughly half what a UK-registered S4 pays Hard to find in this condition now, and the V8 noise is something the turbo cars can't match.
