The AUDI A4 (2001-05) 4DR SALOON 2.0 FSI SPORT MTRON AUTO is a premium mid-sized four-door saloon, aimed at buyers wanting a refined alternative to mainstream family cars. Its understated styling and comfortable cabin suit everyday commuting and longer journeys, while the automatic gearbox makes stop-start traffic easier. In the UK used market, it sits among established executive saloons. The mycarcheck.com sample is modest but useful: 22 look-ups covered seven distinct VINs. Those checks show an average recorded mileage of 97,000 miles and average annual use of 3,000 miles, suggesting many examples are now lightly driven. The average private-sale valuation was £400, and cars had about 4.5 previous keepers on average, so condition and history deserve close attention. Compared with BMW 3 Series and Mercedes C-Class rivals, the A4 is known for a composed ride, finish and solid feel. It suits commuters or couples seeking premium motoring, but check maintenance.
