The BMW Z4 (2013-18) is a premium two-seat roadster: a compact, rear-wheel-drive sports car with a folding hardtop, rather than a practical family hatchback or SUV. In the UK used market, it appeals to drivers wanting open-air fun and a more distinctive alternative to everyday cars. Mycarcheck.com records 3,560 look-ups covering 1,517 distinct VINs, giving a substantial snapshot of cars shoppers are researching. The average private-sale valuation is £11,700, with average recorded mileage of 48,000 miles and annual mileage of 4,000. Cars have had around 2.5 previous keepers on average. The Z4 suits singles or couples seeking a stylish weekend car or enjoyable commuter, but its two seats and limited luggage space make it less suited to family duties. Its styling, rewarding drive and retractable hardtop set it apart from soft-top rivals such as the Audi TT Roadster and Mercedes-Benz SLK, blending coupe comfort with the option of open-air motoring.
