The BMW 5 SERIES (2007-10) 525D 4DR SALOON 3.0 197 M SPORT BUSINESS EDITION STEP AUTO is a diesel saloon positioned above mainstream family cars in the UK market. M Sport styling and an automatic gearbox give it an executive feel, with generous cabin space and a conventional boot. It suits commuters and families seeking relaxed long-distance travel, while its size and diesel engine are less geared to short urban trips. mycarcheck.com records 300 look-ups covering 108 distinct VINs, a useful sample; the average private-sale valuation is £3,200, and average recorded mileage is 130,000 miles. Checks also show around 10,000 miles driven annually and nearly five previous keepers on average, so review each car’s history carefully. The 525d’s strong diesel character, comfort and M Sport appearance make it a compelling alternative to an Audi A6 or Mercedes-Benz E-Class, but condition matters: verify servicing, mileage and smooth automatic operation before buying.
