The AUDI A4 (2008-12) 4DR SALOON QUATTRO 2.0 TDI CR DPF 170 SE is a premium, four-door family saloon, sitting in the same competitive UK class as the BMW 3 Series and Mercedes-Benz C-Class. It combines understated styling with a practical cabin and all-wheel-drive traction, making it a more sure-footed choice than many ordinary saloons. Mycarcheck.com has recorded 132 look-ups covering 61 different VINs, a useful pool of used-car interest. Across those checks, the average private-sale valuation is £4,200, while recorded mileage averages 129,000 miles and annual use about 9,000 miles. The cars have had an average of just over four previous keepers, so checking each car’s history and condition is especially worthwhile. This A4 suits commuters and small families wanting refinement, long-distance comfort and diesel range, with Quattro grip adding reassurance in poor weather. It feels more substantial than mainstream alternatives, though buyers should budget for age-related maintenance costs.
