The BMW 3 SERIES COMPACT (2001-05) 320TD 3DR COMPACT 2.0 SPORT EU4 is a premium-feeling, three-door diesel hatchback, combining familiar 3 Series character with a shorter body. In the UK used-car market, it is a distinctive alternative to compact choices such as the Volkswagen Golf and Audi A3, adding a sportier, rear-wheel-drive feel. Mycarcheck.com has recorded 96 look-ups covering 42 different VINs, with an average recorded mileage of 154,000 miles and about 7,000 miles driven annually. The cars checked averaged just over six previous keepers and a private-sale valuation of £500. These figures describe the checked examples, not every car, so condition and service history matter greatly. This compact suits commuters or drivers wanting an economical diesel for regular journeys, while its three doors make it less convenient for families needing rear-seat access. Sport trim and BMW’s driving feel set it apart, but at this age, inspect carefully before buying.
