The BMW 3 SERIES (1998-06) 330D 4DR SALOON SPORT is a four-door diesel saloon from the executive end of the used-car market. It sits below larger luxury models while offering more space and presence than a typical family hatchback. In the UK, it appeals to drivers seeking a traditional premium car. Mycarcheck.com has recorded 18 look-ups covering 11 distinct VINs, a modest sample rather than a market survey. Those checks show average recorded mileage of 154,000 miles, annual use of around 7,000 miles, and about 6.6 previous keepers. Average private sale valuation was £500, a notable low figure for its age. With relaxed diesel performance and an engaging feel, the 330d suits commuters and small families wanting comfort, space and motorway travel. It feels more involving than many rivals, including the Audi A4 and Mercedes-Benz C-Class. Check condition and service history carefully; the mileage and keeper figures make an inspection worthwhile.
