The BMW 3 Series Compact (2001-05) 320td 3dr Compact 2.0 ES Auto is a premium, three-door hatchback, blending the familiar 3 Series feel with a shorter, more town-friendly shape. In the UK used market it sits between mainstream family hatchbacks and pricier compact models such as the Audi A3, offering a distinctive badge and rear-wheel-drive character. Its 2.0-litre diesel and automatic gearbox suit regular commuting and longer journeys, while the compact footprint helps with parking; it is best for singles, couples or small households wanting a more engaging alternative to an ordinary hatchback. The three-door layout and limited rear-seat access make it less convenient for growing families. mycarcheck.com records 13 look-ups across eight VINs. Average mileage is 152,000, with six previous keepers, so check history carefully. The average private-sale valuation was £400, not a guaranteed price. Against Golf and A3 rivals, it offers diesel economy and engaging driving for commuters.
