The BMW 3 SERIES (2005-12) 320I 150 4DR SALOON 2.0 is a compact executive four-door saloon, aimed at buyers wanting a more polished alternative to an ordinary family car. In the UK used market, it sits alongside the Audi A4 and Mercedes-Benz C-Class, combining a smart, understated look with room for everyday passengers and luggage. The 320i suits commuters and small families who value comfortable long-distance travel and a more engaging drive than many mainstream saloons. Its petrol engine offers smooth, responsive performance, while the 3 Series is known for balanced handling and a driver-focused cabin. It is less practical than a hatchback and running costs may exceed those of a smaller family car, so condition and service history matter. Mycarcheck.com recorded 89 look-ups across 28 VINs; averages were 164,000 miles, seven previous keepers and a £1,300 valuation. These figures offer context, not a guarantee for any individual car.
