The BMW 3 SERIES (1998-06) 318D 4DR SALOON 2.0 115 SE is a compact executive saloon: a four-door, rear-wheel-drive family car with a more upmarket feel than ordinary small saloons. In the UK used market, it sits alongside period Audi A4 and Mercedes-Benz C-Class models, offering BMW’s familiar, driver-focused character in a practical shape. With a diesel engine and SE trim, this 318d is suited to regular commuting, longer journeys and small families wanting a comfortable saloon rather than a hatchback. Its modest power is best appreciated for steady everyday driving, while the 3 Series’ balanced road manners and tidy styling help it feel engaging and distinctive. Compared with mainstream family cars, it brings a more premium cabin and badge appeal, though age and condition matter greatly when shopping. Across 75 checks and 28 VINs, mycarcheck.com shows £900 average private value, 129,000 miles, 7,000 annual miles and 8.24 previous keepers on average.
