The BMW 3 SERIES (1998-06) 330D 4DR SALOON SE is a compact executive four-door saloon, offering a more premium alternative to mainstream family cars in the UK used market. It sits alongside the Mercedes-Benz C-Class and Audi A4, with discreet styling, a useful boot and space for everyday passengers and luggage. Mycarcheck.com records 161 look-ups covering 62 VINs, a solid sample for this model. Checks show an average private-sale valuation of £600, recorded mileage of 176,000, annual mileage of 15,000 and 6.6 previous keepers. These figures describe checked examples, not a guarantee of condition or a price for any individual car. Its diesel engine makes the 330d well suited to longer commutes and motorway trips, while the saloon format works for couples or families wanting comfort and performance. It is best for buyers valuing a composed drive over low running costs. Age, mileage and service history matter, so inspect before purchase.
