Our Verdict
We recommend considering this 2021 Mazda MX-5, given its low mileage and recent MOT history. The single recorded failure was due to a headlamp aim issue, which is a relatively minor problem. Overall, this vehicle appears to be a solid choice for those seeking a reliable, petrol-powered sports car.
When purchasing this vehicle, be sure to review the service history to ensure that the headlamp aim issue was properly addressed. Additionally, consider negotiating the price based on the minor MOT failure. It is also essential to check the vehicle's maintenance records to confirm that regular servicing has been performed. As with any used vehicle, a thorough inspection is crucial to identify any potential issues. The MX-5's petrol engine and manual transmission are generally reliable, but it is still important to check for any signs of wear or damage.
As a petrol-powered vehicle, this Mazda MX-5 will likely have moderate running costs. With an engine size of 1496.0cc, it should be relatively fuel-efficient, especially for a sports car. The estimated annual running cost is £800-£1,000, covering fuel, tax, insurance, and typical maintenance. Insurance costs may be higher due to the vehicle's sports car classification, but this can vary depending on the driver's profile and location. Regular servicing and maintenance will help to keep costs under control.
When inspecting this vehicle, pay close attention to the headlamps and ensure that the aim is properly adjusted. Additionally, check the vehicle's body and paintwork for any signs of damage or wear, particularly given its blue colour. The 1496.0cc engine should be in good condition, but it is still essential to check for any signs of leaks, worn belts, or other issues. A test drive will help to identify any potential problems with the transmission or suspension. As with any used vehicle, a thorough inspection is crucial to identify any potential issues before making a purchase.
This 2021 Mazda MX-5 has a clean bill of health, with the exception of a single MOT failure in 2024 due to a headlamp aim issue. With a mileage of 11826 miles as of the last MOT test, this vehicle has been driven relatively sparingly. The blue colour and 1496.0cc petrol engine make it an attractive option for those seeking a fun, fuel-efficient driving experience. As a 2021 model, it is likely to have many of its original manufacturer warranties still in effect.
No aggregate data is available for the Mazda MX-5 model, so it is difficult to assess its overall reliability. However, the fact that this vehicle has only had one minor MOT failure suggests that it may be a reliable choice.

- Rear Suspension Hub Carrier Spherical Bushing Play and ClunkingModerate
The multi-link rear suspension on the ND MX-5 uses spherical bearing pillow-ball bushings within the aluminium rear hub carriers (knuckles) to control wheel geometry. Over UK roads, moisture, road salt and grit penetrate the rubber dust seals, causing the internal spherical joints to corrode and develop excessive play. This produces a noticeable rear-end knocking noise over bumps, vague high-speed stability, and an automatic UK MOT failure for excessive play in a suspension pin, bush or joint. Mazda does not supply replacement bushes separately, quoting £900–£1,600 to replace complete hub assemblies; however, independent specialists fit aftermarket polyurethane or spherical replacement bush kits (such as Polybush or Powerflex) on the car.
- Soft Top Fabric Contact on Roll Hoop Covers and Premature FrayingModerate
On soft-top ND models, the folding roof frame geometry and tight clearances allow the canvas fabric to rub directly against the sharp edges of the plastic headrest roll hoop covers (seat-back bar garnishes) as the roof is lowered or raised. Repeated friction abrades the outer cloth fibres, creating visible whitening, scuffing and eventual through-holes in the fabric just behind the front edge. Mazda issued Technical Service Bulletin 09-023-19 to address roof contact, modifying link stoppers and clearances under warranty. On used cars out of warranty, fitting aftermarket clearance spacers, protective felt tape or replacing damaged hood sections is necessary.
- Roof Drain Trombone Filter Blockage and Cabin Water IngressModerate
The ND MX-5 utilizes rainwater collection basins with integrated one-way flap valves and removable debris filters located behind each seat belt tower. In the UK climate, pine needles, pollen, road grit and tree leaves easily bypass the grills and clog the narrow plastic drain tubes. When blocked, rainwater cannot drain under the car and overflows down into the cabin, accumulating under the rear parcel shelf insulation and soaking the front footwell carpets. Standing water can submerge the audio wiring loom and the sensitive Bose audio amplifier or control modules mounted under the seat, creating severe electrical corrosion and musty damp odors.
