The BMW 3 SERIES (2005-12) 320D 177 4DR SALOON 2.0D ES is a premium, four-door family saloon, aimed at buyers wanting something more polished than an ordinary mid-size car. In the UK, it sits among established executive-style choices, offering a practical boot and seating for everyday journeys, without the bulk of an SUV. Mycarcheck.com has recorded 520 look-ups covering 184 distinct VINs, a useful sample of interest rather than a complete picture of every car. Checks show an average private-sale valuation of £2,000 and average recorded mileage of 133,000 miles. The cars average 7,000 miles yearly and nearly five previous keepers, so condition and history deserve close attention. The 320d suits commuters and small families, with comfortable journeys, good diesel economy and an engaging drive. The BMW 3 Series is a premium-feeling rival to the Audi A4 and Mercedes-Benz C-Class; check service history carefully when buying for a well-kept example.
