The AUDI A4 (2011-15) 4DR SALOON QUATTRO 2.0 TDI DPF SS 177 EU5 SE 6SPD is a premium four-door family saloon in the UK market, competing with the BMW 3 Series and Mercedes-Benz C-Class. Its restrained design and comfortable cabin offer a more polished alternative to a mainstream family hatchback. Mycarcheck.com has recorded 23 look-ups covering 11 different cars, so the figures offer a useful snapshot rather than a large survey. The average private-sale valuation is £6,400, with recorded mileage averaging 111,000 miles and annual use around 9,000 miles. Checks show about three previous keepers on average, making history checks worthwhile. With diesel economy and quattro traction, this A4 suits commuters and families seeking comfort, useful space and confidence in poor weather. The A4 feels composed and premium, rather than flashy, and is a compelling used rival to German saloons. Before buying, check service history and whether its diesel filter was maintained.
