The AUDI A4 (2001-05) 5DR AVANT 1.8T 163 SE MTRON AUTO is a premium estate, offering generous luggage space and everyday usability. In the UK used-car market, it competes with practical, upmarket rivals such as the BMW 3 Series Touring and Volvo V50, for buyers seeking comfort and carrying room. With a turbocharged petrol engine and automatic transmission, the A4 suits drivers wanting relaxed journeys, carrying capacity and a refined feel. It can work well for couples, small families, commuters and weekend travellers, although age, fuel use and upkeep deserve attention when choosing a used example with a full history. Mycarcheck.com recorded 11 checks covering seven different VINs, so figures are clues rather than a broad market picture. Checked cars averaged 143,000 miles and 5,000 miles a year, with around six previous keepers; average private-sale valuation was £400. These older-car averages make history and condition checks especially worthwhile before purchase.
