The BMW 7 SERIES (2002-08) 730D 4DR SALOON 3.0D 231 SE STRATUS EXCLUSIVE AUTO is a large, luxurious four-door diesel saloon, sitting near the top of the UK used-car market. It was built for comfort and presence rather than city-car practicality, offering a spacious cabin and a relaxed, refined feel suited to business travel and long motorway journeys. mycarcheck.com records 13 look-ups covering four distinct VINs, so the sample is useful but relatively small. Across those checks, average private-sale value was £2,600, average recorded mileage was 150,000, and typical annual mileage was 11,000. Cars averaged just over four previous keepers, making a history check especially worthwhile. Against S-Class and Audi A8 rivals, the 730d stands out for comfort, motorway cruising and an involving drive. Its roomy cabin and generous equipment suit executives, experienced drivers and families seeking a refined long-distance car. Check condition and service history: upkeep and fuel costs can be significant.
