The BMW 3 SERIES (1998-06) 320D 4DR SALOON 2.0 REV 01 is a compact executive four-door saloon, offering a more premium alternative to mainstream family cars. In the UK used market, it sits alongside models such as the Audi A4 and Mercedes-Benz C-Class, combining smart styling with useful everyday practicality. Six mycarcheck.com look-ups covered six different VINs, so the sample is small but offers a useful snapshot: the average recorded mileage was 183,000, with around 8,000 miles driven annually. Cars checked had an average of 5.5 previous keepers and an average private-sale valuation of £400, so condition and history matter greatly. This diesel BMW suits commuters and small families wanting a car for regular journeys, with a roomy cabin and boot. Its long-distance economy and composed, enjoyable drive helped make the 3 Series a class favourite against rivals.
