The AUDI A4 (2001-05) 4DR SALOON 1.8T 163 SPORT is a compact executive four-door saloon, aimed at buyers wanting a more premium alternative to mainstream family cars. In the UK used market it sits alongside the BMW 3 Series and Mercedes C-Class, offering a smart, understated look with everyday practicality. The 1.8-litre turbo petrol engine gives this Audi A4 a brisk, enjoyable feel, while the Sport trim brings a more purposeful character. It suits commuters and couples or small families needing a comfortable car for regular journeys, though running costs and age deserve consideration. Its cabin and composed road manners helped make the A4 a familiar rival to premium saloons. mycarcheck.com records 100 look-ups covering 54 distinct VINs, giving a snapshot rather than a full picture.
