The BMW Z4 (2009-13) SDRIVE20I 2DR ROADSTER 2.0 184 EU5 M SPORT AUTO8 is a two-seat, open-top sports car, rather than a practical family hatchback or everyday SUV. In the UK used-car market, it appeals to drivers seeking premium style and enjoyable weekend motoring, with an automatic gearbox making relaxed town and motorway trips easier. Mycarcheck.com records 340 checks covering 132 distinct VINs, a substantial research sample. The average private-sale valuation is £10,700, while recorded mileage averages 65,000 miles and annual use is around 4,000 miles.
