The BMW 3 SERIES (2005-12) 320I 150 4DR SALOON 2.0 ES AUTO is a compact executive saloon: a four-door petrol family car for buyers wanting more polish than an ordinary hatchback. In the UK used market, it sits among established premium rivals such as the Audi A4 and Mercedes-Benz C-Class, offering a comfortable, upmarket alternative. It suits commuting, longer journeys and small-family duties, with an automatic gearbox making busy traffic easier. Mycarcheck.com has recorded 85 look-ups across 38 VINs, a useful sample of buyer interest, though not a measure of every car. Checks show average mileage of 101,000 and about 6,000 miles driven yearly. The data suggests an average private-sale value of £1,800 and 5.2 previous keepers, so check each car’s history and condition; these are sample averages, not guarantees. The 320i is known for balanced road manners and a cabin, offering an engaging feel compared with mainstream saloons, though running costs can be higher.
