The AUDI A4 (2005-08) 4DR SALOON 2.0 130 S LINE MTRON AUTO is a compact executive four-door saloon, offering a polished, grown-up alternative to mainstream family cars. In the UK used market, it sits alongside models such as the BMW 3 Series and Mercedes-Benz C-Class, appealing to drivers wanting a premium badge without a new-car price. Mycarcheck.com recorded 138 look-ups covering 42 different VINs, giving a useful snapshot of interest. The checks show average mileage of 123,000 and average annual use of 5,000 miles; the average private-sale valuation is £1,000. Vehicles had an average of around seven previous keepers, so condition and history deserve careful checking. The S line trim gives the A4 a sportier look, while its automatic gearbox can make commuting and stop-start trips relaxed. Its cabin and boot suit couples or families, but age, running costs and keeper count make a thorough inspection important against rivals.
