2004 BMW Z4 2.2L Petrol · SH54 MRO

The most recent MOT test on July 18, 2023, confirmed this 2004 BMW Z4 as roadworthy at 108,626 miles, with no defects or advisories recorded. The preceding test in April 2022 also passed without issues, indicating a stable maintenance pattern over the past three years. While the absence of failures suggests the vehicle has not experienced major mechanical or structural problems during these intervals, the age of the car—now approaching 22 years—demands a thorough inspection of high-wear components that are not routinely captured by the MOT. The lack of advisories in either test is notable, as this typically signals either diligent servicing or deferred maintenance that has yet to manifest in overt failures. The recorded mileage of 108,626 miles over roughly 22 years equates to an average of approximately 4,938 miles annually, which is unusually low for a vehicle of this age. The gap between tests—13 months between April 2022 and July 2023—aligns with the standard MOT cycle, but the preceding interval from July 2021 to April 2022 (12 months) was similarly compliant. There is no evidence of rapid mileage accumulation or prolonged periods of inactivity, though the low annual mileage could imply the car has spent extended periods stored or used infrequently. This may contribute to potential issues such as degraded fluids, seized components, or corrosion from moisture exposure, which are not always visible without a detailed inspection. Given the car’s age and the absence of MOT advisories, a buyer should prioritise examining critical wear items that are not routinely tested. The suspension—particularly the coil springs, bushes, and dampers—should be inspected for uneven wear, leaks, or binding, as these are common failure points in high-mileage or aged vehicles. Brake components, including discs, pads, and calipers, warrant close scrutiny for uneven wear, corrosion, or binding, especially if the vehicle has experienced periods of disuse. Structural integrity is another concern; the chassis, subframe, and wheel arches should be checked for corrosion, particularly around the rear axle and wheel housings, where salt damage is often severe. Finally, the exhaust system should be inspected for leaks or excessive rust, as these can contribute to failing emissions tests or structural compromise. While the MOT history is clean, these areas are where deferred maintenance or age-related deterioration could pose risks.
