The AUDI RS6 (2008-11) RS6 4DR SALOON QUATTRO 5.0 TFSI V10 580 PLUS TIP AUTO6 is a rare, high-performance saloon: an executive-sized car with supercar pace, rather than an everyday hatchback or SUV. In the UK used market, it sits at the specialist, premium end of fast family cars. Mycarcheck.com records show 24 look-ups covering six distinct VINs, so this is a small sample, not a full picture of every car. Within those checks, average private-sale valuation was £26,100, recorded mileage averaged 71,000 miles, and annual mileage was about 2,000 miles. Cars had around 2.7 previous keepers on average. Its V10 engine, four-wheel drive and automatic gearbox deliver all-weather speed, while the saloon body and four doors make it usable for family trips and commuting. It suits enthusiasts wanting performance with space, not running costs. Against BMW M5 and Mercedes-AMG rivals, the RS6 is prized for power and Audi style.
