The BMW 5 SERIES (1996-03) 525D 4DR SALOON 2.5D ES AUTO is a sizeable, four-door executive saloon: a comfort-focused alternative to a family hatchback, positioned in the UK against cars such as the Mercedes-Benz E-Class and Audi A6. Its understated shape and roomy cabin make it a useful long-distance companion. Its automatic gearbox and diesel engine suit commuters, couples or families seeking a relaxed car for motorway journeys, rather than a small first car. The ES trim adds comfort-minded appeal, and the 5 Series is known for a composed ride and a more engaging drive than many executive rivals. mycarcheck.com has recorded seven checks across four distinct VINs, so these figures offer a small snapshot, not a market-wide verdict. Checked examples averaged £1,300 in private-sale value, 158,000 miles and about 6,000 miles a year; the average keeper count was nearly six, worth bearing in mind when assessing condition and history.
