A lauded high-performance sedan, this C5-generation Audi RS6 combines practical versatility with formidable power from its twin-turbocharged V8. It is powered by a 4.2-litre twin-turbocharged V8, delivering its power to all four wheels via a five-speed automatic transmission. First registered in Australia in April 2003, this RS6 has been with the seller for two years. The odometer shows 157,401 Kms from new. Build year: 2003 This C5-era RS6 Sedan is finished in the refined shade of Silver Blue, over a black leather-trimmed interior, featuring Recaro seats, embossed ‘RS6’ emblems on the seat backs, white seat piping, and brushed aluminium-effect and carbon-fibre trim. It rides on an aftermarket set of 19-inch twin five-spoke alloy wheels finished in satin-black, framing gloss-black RS-branded brake callipers, and fitted with Winrun tyres. Equipment includes projector headlights, front and rear parking sensors, an electric rear sun blind, an Audi Navigation Plus media system, dual-zone automatic air conditioning, an electric sunroof, heated rear seats, cruise control, a Bose sound system, and electrically adjustable heated front seats. This example has been enhanced with a set of DGR coilover suspension. The car is accompanied by the original owner’s handbooks with a black leather wallet, a warning triangle, the DGR coilover instruction manual, an A4 folder containing a large collection of maintenance and parts invoices, and two remote keys. Please refer to the photo gallery to assess the exterior and interior condition. Specific notes from the seller include: the interior roof lining has begun to sag slightly at the rear, and the front bumper has previously been repainted. This RS6’s most recent routine maintenance was carried out in May 2025 at around 157,000 km by JLA Automotive, including a full service after the gearbox was reinstalled. The gearbox was rebuilt following a failure in June 2024, with the car subsequently off the road until March 2025, awaiting parts and reinstallation. The timing belt was replaced in August 2023. Other notable maintenance includes new engine mounts being installed and the air conditioning being regassed. This Audi RS6 is a well-presented example of the very capable C5-generation performance sedan, benefitting from recent mechanical refurbishment including a gearbox rebuild, suspension overhaul, and timing belt service. It combines muscular twin-turbocharged V8 performance with everyday usability, making it ideal for an enthusiast seeking a fast yet practical modern classic for retro daily driving and long-distance road trips alike.
