The BMW 3 SERIES (1998-06) 330D 4DR SALOON SPORT EU4 AUTO is a four-door, premium compact saloon: a more driver-focused alternative to mainstream family cars, rather than a hatchback or SUV. Its Sport trim and automatic gearbox give this 3 Series a relaxed character, while the diesel engine suits longer journeys. Mycarcheck.com has recorded 318 look-ups covering 129 different VINs, a useful sample of interest in this model. Checks show an average most recent mileage of 143,000 miles and around 5,000 miles annually; the average is about six previous keepers. Average private-sale valuation is £1,200, so condition and history matter greatly. It suits commuters and small families wanting a comfortable motorway car with more punch than ordinary diesel saloons; the automatic eases traffic. Against the Audi A4 and Mercedes-Benz C-Class, the 330d is known for an engaging drive and strong, flexible performance. At this age, inspect condition and history carefully.
