The BMW Z4 (2013-18) SDRIVE20I 2DR ROADSTER 2.0 SS 184 EU6 6SPD is a two-seat, open-top sports car, rather than a practical family hatchback. In the UK used market it sits among premium roadsters, offering BMW badge appeal and everyday usability for drivers who want a special weekend car. mycarcheck.com has recorded 295 look-ups for this model, covering 82 distinct vehicles. In that sample, the average private-sale valuation is £9,800, average recorded mileage is 53,000 miles and annual mileage is 4,000. Cars averaged about 2.4 previous keepers; these figures describe checks, not a guarantee for any individual Z4. Folding hard roof makes the Z4 secure and refined compared with a fabric-top roadster, while retaining open-air fun and an engaging drive on winding roads. It suits couples, enthusiasts or commuters who rarely need rear seats. Against the Audi TT Roadster and Mercedes-Benz SLK, its distinctive styling and BMW driving character stand out.
