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.

We have limited data for the 2021 Ford Mustang Mach 1 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
