The BMW 3 SERIES (2005-12) 318D 143 4DR SALOON 2.0D DPF EXCLUSIVE EDITION 6SPD is a compact executive saloon: a premium four-door family and business-commuter car, rather than a hatchback or SUV. Its smart, understated design and practical cabin and boot put it alongside the Audi A4 and Mercedes-Benz C-Class in Britain. It suits commuters and small families who want a comfortable, composed drive, rear doors and long-distance diesel economy; the 143bhp engine and six-speed manual make it a motorway companion. The DPF-equipped diesel is best for drivers who take longer journeys, while buyers should check its service history and emissions equipment. mycarcheck.com has recorded 871 checks covering 379 different cars, a sample; average recorded mileage is 126,000, with 9,000 miles added yearly and about four previous keepers. The average private-sale valuation is £3,200. Against rivals, this 3 Series is known for engaging handling and a balanced, premium feel, though condition matters.
