The BMW 3 SERIES (1998-06) 318D 4DR SALOON 2.0 115 ES is a four-door diesel family saloon from BMW’s long-running 3 Series range. It sits in the UK’s premium compact-car market, offering an alternative to hatchbacks and a smaller, manageable choice than a large executive car for everyday motoring. Mycarcheck.com recorded 161 look-ups across 63 different VINs, giving a sample of interest in this model. In those checks, average private-sale value was £800, average mileage was 121,000, and cars had averaged about 10,000 miles yearly. The typical example showed nearly six previous keepers, so check each car’s history carefully. It suits commuters and families wanting comfortable motorway travel, a drive and boot of a saloon, while diesel economy can help regular-distance drivers. Against Audi A4 and Mercedes-Benz C-Class rivals, the 3 Series is known for an engaging feel and premium image. Age, condition and service history matter when buying.
