2021 Ford Mustang Mach 1
CarHunch analysed 138 real MOT records for the 2021 Ford Mustang Mach 1. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Ford Mustang Mach 1 is a genuinely reliable performer on the MOT, with a 90.2% first-time pass rate that sits 10 points above the UK average of 80%. Dangerous defects are uncommon at 7.2%, so safety-critical issues are not a concern for buyers in this cohort.
At just over 12,000 miles median mileage, these cars are relatively lightly used for their age, and they're living up to that gentle treatment—the average vehicle has only 0.22 failures and 0.9 advisories on test, suggesting well-maintained examples. Before buying, have any specific example independently inspected for wear items like brakes and suspension, as advisories at this rate hint at normal maintenance needs rather than structural problems.
What to check before buying a 2021 Ford Mustang Mach 1
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.
