The BMW 3 SERIES (2005-12) 320I 150 4DR SALOON 2.0 ES is a four-door petrol executive saloon and a more refined alternative to a family hatchback. In the UK used-car market it competes with premium compact saloons such as the Audi A4 and Mercedes-Benz C-Class. It balances comfort and driver appeal. mycarcheck.com records 393 look-ups across 176 distinct VINs. Checks show an average recorded mileage of 120,000 miles and average annual use of 5,000 miles; the average private-sale valuation is £1,500. Owners have averaged around 6.6 previous keepers, making an individual vehicle’s history and condition especially worth checking before you buy. Suited to commuters and small families, it offers comfort, four doors and usable rear seats. Its 150hp petrol engine feels smooth and engaging, with more polish than mainstream saloons, though fuel and upkeep may cost more. The ES is a restrained BMW choice; check condition and service records carefully, too.
