The BMW Z4 (2003-09) 2DR ROADSTER 3.0I 231 SE AUTO is a two-seat, open-top sports car, rather than a practical family hatchback. In the UK used-car market it offers a more premium, performance-focused alternative to everyday convertibles, with an automatic gearbox that can make relaxed cruising easier. Its long bonnet and compact cabin give it a distinctive roadster look. mycarcheck.com has recorded 374 look-ups across 144 distinct VINs, a useful sample of interest, though not a full picture of every car. Checks show an average private-sale valuation of £2,700 and average recorded mileage of 95,000 miles. Average annual mileage is relatively low at 2,000 miles, while cars have had about six previous keepers on average. It suits weekend drives and trips for couples, not families needing space. Its open-air character and engaging drive distinguish it from rivals such as the Mercedes-Benz SLK; check condition and service history carefully before buying.
