The AUDI A6 (2011-15) 4DR SALOON QUATTRO 3.0 TFSI SS 300 EU5 SE STRON AUTO7 is a large, premium four-door saloon, aimed at buyers seeking more comfort and space than a mainstream family car. In the UK it sits in the executive-car class, alongside the BMW 5 Series and Mercedes-Benz E-Class. Its petrol engine, automatic gearbox and quattro all-wheel drive make it a particularly powerful, assured option. It suits professionals, couples and families who want a refined commuter or comfortable long-distance car, with useful cabin space and confident grip in poor weather. The 3.0-litre petrol version prioritises smooth, lively performance over low running costs, so buyers should budget for fuel and check service history carefully. In mycarcheck.com data, 24 checks covered 14 distinct cars; recorded examples averaged 70,000 miles, 5,000 miles a year and just over two previous keepers. The average private-sale valuation was £5,900, a helpful guide, not a promise.
