Should I check the MOT history before buying a 1991 BMW M3?

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 1991 BMW M3 passes its MOT first time at 83.3%, which is a solid 3.3 percentage points above the UK average, suggesting these cars are reasonably well-maintained overall—though 11.4% have recorded dangerous defects, so a pre-purchase inspection by a specialist is wise. These M3s are sitting at around 130,000 miles on average, which is predictable for a 33-year-old classic, and they're picking up 1.24 failures and 5.0 advisories per test, pointing to wear in non-critical areas rather than systemic problems.

If you're buying one, budget for incremental repairs (worn suspension, trim bits, seals) rather than major overhauls, but always have a trusted BMW specialist give it a thorough once-over first—the 11.4% dangerous defect rate means corners do get cut on some examples.
