The BMW Z4 (2003-09) 2DR ROADSTER 2.0I 150 SE is a compact, two-seat convertible sports car, rather than a practical hatchback or family car. In the UK used-car market, it offers open-top motoring with premium-badge appeal, often at an accessible older-car price. Mycarcheck.com has recorded 1,499 checks across 524 distinct VINs, giving a useful snapshot of interest in this model. Across checks, average private-sale valuation is £2,200, with average recorded mileage of 103,000 and annual use around 3,000 miles. The average keeper count is about seven, so check service history, condition and ownership details carefully; these figures are guideposts, not guarantees for any individual car. Its long bonnet, low stance and lively driving feel give it a focused, engaging character. Best suited to couples or drivers seeking a weekend escape, the Z4 is less convenient than rivals such as the Mazda MX-5 for budgets, but feels upscale.
