The AUDI A4 (2001-05) 4DR SALOON 2.5 TDI 155 SPORT MTRON AUTO is a premium, four-door family saloon, rather than a hatchback or SUV. In the UK used-car market, it sits among established executive cars, offering a more upmarket feel than ordinary family transport while remaining practical for everyday driving too. mycarcheck.com recorded seven look-ups across three distinct VINs, a small snapshot rather than a definitive market picture. Checked cars averaged 118,000 miles, about 3,000 a year, and just under three previous keepers; average private-sale valuation was £400. These are historical check-data averages, not a current price guide for this model. With Sport trim, strong diesel performance and automatic convenience, this A4 suits commuters and small families making longer trips. It is known for a composed, refined drive and premium presentation, competing with BMW 3 Series and Mercedes C-Class saloons. Check age and condition: they matter on any older model.
