2004 BMW Z4 2.2L Petrol · 500 EP

The 2004 BMW Z4 presents a highly stable and reassuring maintenance trend, culminating in a completely clean pass at its most recent MOT on 18 June 2025 at 30,237 miles. The tester recorded zero defects, advisories, or failures, indicating the vehicle currently meets all required safety and environmental standards. This unblemished run of passes demonstrates consistent mechanical care, with no recurring faults or emerging issues to suggest neglect or deferred maintenance. The mileage accumulation is exceptionally low and remarkably consistent, reflecting a vehicle used sparingly rather than sitting entirely dormant. Between the 2022 test at 29,594 miles and the 2023 test at 29,740 miles, the Z4 covered just 146 miles. The following year saw 289 miles added by June 2024, and the most recent annual interval added 208 miles by June 2025. This equates to an average of roughly 200 miles per year over the recorded period, confirming the ultra-low annual usage implied by the 30,237-mile total. Despite the flawless MOT record, a buyer must inspect the vehicle in person for the specific ailments that afflict low-mileage, aging convertibles. Extended periods of standing can cause brake discs to surface corrode and suspension bushes to perish or crack, even if the car passes its roadworthiness checks. Tyre age is a critical concern; the rubber may possess legal tread depth but could suffer from sidewall cracking or flat-spotting due to prolonged static loading. Structural integrity requires a thorough underside inspection. While the MOT covers corrosion, a 22-year-old roadster demands scrutiny of the sills, subframes, and jacking points for any signs of rust that might not yet constitute a failure but indicate long-term exposure. The lack of mechanical advisories suggests the previous owner maintained the car well, but the physical effects of minimal use remain the primary risk factor for this particular example.
