Should I check the MOT history before buying a 1999 Ford Mustang?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 1999 Mustang's first-time pass rate of 81.2% sits just above the UK average of 80%, suggesting broadly average reliability for a car of this age—but the concerning note is that nearly a quarter (24.2%) have experienced dangerous defects at some point, which is notably high and warrants pre-purchase inspection by a specialist. Petrol is the only fuel type in this cohort, and it performs at the overall rate.

These Mustangs are averaging 78,815 miles, which is reasonable for a 25-year-old American import, though the typical failure count of 2.12 per vehicle suggests structural issues beyond wear-and-tear consumables. The real story is in the advisories: 9.1 per car on average points to widespread minor corrosion, trim deterioration, and systems needing attention. Before committing to purchase, have a pre-sale inspection focus specifically on chassis condition and underbody corrosion, as these cars seem prone to accumulating small defects that add up.

We have limited data for the 1999 Ford Mustang — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 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.
