2021 Mazda Mx 5
CarHunch analysed 290 real MOT records for the 2021 Mazda Mx 5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Mazda MX-5 is exceptionally reliable, with a 95.7% first-time pass rate that crushes the UK average of 80%—and dangerous defects are virtually non-existent at just 1.7% of cars. This is a genuinely dependable roadster with no meaningful petrol/diesel split to worry about.
At just under 15,000 miles median mileage, these are lightly used examples, and the 0.12 average failures per vehicle confirms most aren't battling serious mechanical issues. If you're considering one, focus your pre-purchase inspection on the single advisory item that appears per car on average—likely routine wear—and you'll probably find a well-sorted machine.
What to check before buying a 2021 Mazda Mx 5
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
