BMW Z4 (2011)

2,122 real MOT outcomes analysed • 85.9% first-time pass rate

2011 BMW Z4

CarHunch analysed 2,122 real MOT records for the 2011 BMW Z4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2011 BMW Z4 passes its MOT at 85.9%, which is a solid 5.9 percentage points above the UK average, suggesting these sports cars are being maintained reasonably well by their owners. However, nearly half of all Z4s in this cohort—46.1%—have recorded a dangerous defect at some point, which is a serious concern for any prospective buyer and warrants a thorough pre-purchase inspection.

At just under 47,000 miles on average, these Z4s are running relatively low mileage for their age, indicating they're often weekend or leisure vehicles rather than daily drivers. The average vehicle still picks up 2 failures and 9.4 advisories per test, pointing to wear in suspension, lighting, and trim components—typical of aging sports cars—so budget for ongoing maintenance when you buy one.

What to check before buying a 2011 BMW Z4

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.
  • ⚠️ 46.1% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
