The BMW 5 SERIES (1996-03) 523I 4DR SALOON 2.5 SE is a large executive saloon from BMW’s well-regarded 5 Series range. In the UK used-car market it sits above mainstream family cars, offering a premium alternative to a Ford Mondeo or Vauxhall Vectra, with room for passengers and luggage. Mycarcheck.com records show 50 look-ups across 34 different VINs in the dataset. The average private-sale valuation was £600, while recorded mileage averaged 144,000 miles; annual mileage averaged 5,000. Cars checked had nearly five previous keepers on average, so condition and history deserve close attention. This 523i suits drivers wanting comfortable long-distance commuting, business travel or a roomy family car, rather than a small, low-cost first car. Its smooth six-cylinder petrol engine and composed ride are key attractions, giving it a more refined feel than many everyday rivals. At this age, a careful inspection and service-history check matter more than the badge.
