The AUDI A4 (2001-05) 4DR SALOON 1.8T QUATTRO SE is a compact executive four-door saloon, offering a more refined, traditional alternative to family hatchbacks. Its turbocharged petrol engine and four-wheel drive give it a distinctive blend of brisk performance and added grip, appealing to drivers who want comfort without choosing a large car. In mycarcheck.com checks, this model has a modest sample of 16 look-ups covering 12 different VINs, so figures are useful indicators rather than a full market picture. The recorded cars averaged 126,000 miles and 3,000 miles a year; average keeper count was 6.25, suggesting many examples have changed hands repeatedly. Best suited to commuters or small families who value sure-footed all-weather driving, the A4 also works as an enjoyable long-distance car. Against BMW 3 Series and Mercedes C-Class rivals, it stands out for traction and comfort. The average private-sale valuation recorded was £300, so check condition carefully.
