The AUDI A4 (2008-12) 4DR SALOON 2.0 TDIE DPF SS 136 SE 6SPD is an executive saloon, a practical four-door positioned above mainstream family cars in the UK used-car market. Its understated styling and comfortable cabin offer a polished alternative to ordinary saloons, while remaining easier to manage than a large luxury car. Mycarcheck.com has recorded 1,619 checks covering 715 different VINs, a sizeable sample. Those checks show an average private-sale valuation of £3,400 and average recorded mileage of 136,000 miles.

The 136hp diesel suits commuting, longer journeys and family duties, with a six-speed manual and efficiency-minded stop-start system helping keep running costs appealing. It competes with BMW 3 Series and Mercedes C-Class saloons, offering a restrained, comfortable drive; check service history and condition carefully at this age.
