The 2021 MX‑5 is the ND family roadster: lightweight, rear‑wheel drive and typically fitted with a 6‑speed automatic from Aisin if it’s an automatic car. Automatic MX‑5s are slightly heavier and a touch less involving than manuals but very usable in town; check whether the car is a soft‑top roadster or the RF retractable hardtop because roof servicing and potential faults differ. Roof seals, boot area and gearbox fluid/service history are the key variant-specific items to note for this drivetrain.

• Roof operation and seals — inspect soft‑top fabric for wear and the rear window for delamination; if RF hardtop, run the roof cycle and check for abnormal noises and seal compression.
• Automatic gearbox behaviour and service history — shifts should be smooth with no hesitation or harsh kickdown; ask for gearbox fluid/change records.
• Front-end stonechips and corrosion — low nose means chips on bumper, bonnet and lower sills; check for paint damage that can lead to rust.
• Suspension and steering bushes — check for knocks over bumps and uneven tyre wear (low cars often hit kerbs or speed ramps).
• Boot/boot‑lid seals and drain channels — water ingress around the boot or under carpets is a common convertible worry.
