The BMW Z4 (2003-09) 2DR ROADSTER 3.0I 231 SE is a compact, two-seat convertible sports car, rather than a practical family hatchback. In the UK used-car market, it sits as an affordable premium roadster, offering open-air motoring and a more distinctive feel than everyday small cars. Its long bonnet and sleek shape give it real presence. mycarcheck.com has recorded 1,064 look-ups covering 391 different VINs, a substantial sample. Checks show an average private-sale value of £2,500 and recorded mileage around 102,000 miles; average annual use is about 3,000 miles. The typical car has had roughly six previous keepers, so review each car’s history and condition carefully: these figures are guideposts, not promises. Ideal for couples or enthusiasts’ weekend drives, the 3.0-litre Z4 offers lively performance, a folding roof and sharper handling than many convertibles. It rivals the Audi TT and Mercedes SLK, favouring sporty character over space or low running costs.
