Our Verdict
This 2021 BMW Z4 presents a low‑risk pro
When viewing the car, verify that the MOT certificates are genuine and match the dates and mileage shown (10,498 miles in Aug 2024, 15,898 miles in Jul 2025, 17,981 miles in Mar 2026). Request any additional service records to confirm regular oil changes and timing belt/chain maintenance, especially given the 2.0‑litre petrol engine.
Negotiate on the basis of typical model wear points such as headlamp lenses, tyre tread depth and brake pad thickness, which are the top MOT failure reasons for the Z4 fleet. Even though this vehicle has no recorded failures, inspecting these components can uncover early signs of wear that may require replacement soon.
Consider the broader cost of ownership for a premium sports car. The Z4 tends to sit in a higher insurance group and road‑tax band, so factor these into your budget alongside fuel consumption. A realistic offer should reflect both the clean MOT history and any upcoming wear‑item replacements.
The 2.0‑litre petrol engine in the Z4 typically delivers around 30–35 mpg combined, meaning fuel costs will be moderate for a sports car but higher than mainstream family cars. Road tax for a 2021 petrol vehicle of this size falls into the £150–£200 band annually.
Insurance groups for the Z4 are usually in the 30s to low 40s, leading to higher premiums than average family saloons. Routine maintenance, including brake pad replacement and tyre wear, can add £300–£500 per year. When combined, the estimated annual running cost sits in the £800–£1,000 range.
Even though the MOT history shows no failures, inspect the headlamps for clouding or moisture, as headlamp issues are the most common MOT failure for the Z4 model. Check the condition of the bulbs and ensure the lenses are clear.
Examine the tyres for tread depth, uneven wear, and sidewall damage. Tyre failures also rank highly in the model's MOT failure data, so confirming adequate tread (minimum 3mm) is essential.
Inspect the brake pads and discs for wear, as brake pad failures are a frequent MOT issue on this model. Look for scoring, glazing, or reduced pad thickness, and ask the seller about the last brake service.
The blue 2021 BMW Z4 has passed three consecutive MOT tests (2024, 2025, 2026) with no recorded defects, indicating no recent statutory failures. Its mileage of 17,981 miles translates to roughly 3,600 miles per year, which aligns closely with the model's average annual mileage of 3,669 miles. While the Z4 enjoys an 83% overall MOT pass rate across the model fleet, the absence of failures on this specific vehicle is a positive sign. Overall, the car offers a typical usage profile for a five‑year‑old sports roadster.
Across 41,484 analysed Z4s, the average MOT pass rate is 83%, suggesting the model generally meets legal standards but does encounter occasional component failures.

- B58 Coolant Loss / PCVModerate
The 3.0-litre turbocharged B58 straight-six engine in M40i models can experience slow coolant seepage from the water pump housing/cap or split the rubber crankcase ventilation (PCV) valve diaphragm integrated into the valve cover.
