The BMW Z4 (2009-13) SDRIVE28I 2DR ROADSTER 2.0 245 EU5 AUTO8 is a premium, two-seat convertible for drivers who want open-air motoring rather than family-car practicality. In the UK used market, it sits among compact luxury sports cars, with a more polished feel than a basic weekend runabout. mycarcheck.com has recorded 15 checks covering eight different VINs, a modest sample that offers a useful snapshot rather than a market-wide picture. The recorded average private-sale valuation is £12,100, with average mileage of 44,000 miles and annual use of 4,000 miles. Checks show an average 2.2 previous keepers. These figures suggest a car often kept for enjoyable, relatively low-mileage driving; individual cars can differ, so check each vehicle’s history and condition. Its retractable hardtop offers security and open-air fun; the automatic gearbox makes cruising easy. Less practical than a Porsche Boxster, the Z4 suits couples, enthusiasts and commuters for relaxed, enjoyable weekend drives.
