The BMW Z4 (2003-09) 2DR ROADSTER 3.0SI 268 SPORT is a two-seat, open-top sports car, not a practical hatchback or family car. In the UK used market, it offers an affordable route into premium roadster motoring, with a distinctive long bonnet and unmistakably sporty shape. Mycarcheck.com has recorded 443 checks covering 142 different VINs. This 3.0-litre Z4 is best suited to couples or enthusiasts who value weekend drives and open-air motoring over rear seats, boot space or low running costs. The average recorded mileage in these checks is 87,000, while annual mileage averages just 3,000, suggesting many examples are used sparingly. Buyers should assess condition and service history, as the average car has had around five previous keepers. Against rivals such as the Mazda MX-5 and Mercedes-Benz SLK, the BMW Z4 stands out for its six-cylinder performance and premium feel. It delivers a more powerful, grown-up take on the roadster idea, while keeping the direct, enjoyable driving experience these cars are known for. The average private-sale valuation is £3,900, though condition matters.
