Ford Mustang (2020)
2020 Ford Mustang
CarHunch analysed 880 real MOT records for the 2020 Ford Mustang. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Ford Mustang is a genuinely reliable performer, with a 90.3% first-time pass rate that sits well above the UK average of 80%—and this holds steady across the petrol variants that make up virtually all the cohort. Dangerous defects are present in 14.5% of vehicles tested, which is below the threshold for serious concern but worth a pre-purchase inspection to rule out.
These Mustangs are running low mileage for their age, averaging just 18,629 miles, which explains the strong pass rates and suggests they're being well-maintained or lightly driven. The average 0.42 failures and 1.8 advisories per vehicle indicate minor wear rather than systemic issues—expect routine maintenance items rather than major repairs when you hit an MOT station.
What to check before buying a 2020 Ford Mustang
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.
