1996 BMW 520

CarHunch analysed 1,743 real MOT records for the 1996 BMW 520. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1996 BMW 520 passes its MOT first time only 67.8% of the time, well below the UK average of 80%, and a quarter of these cars have experienced dangerous defects at some point—a genuine concern for buyers. The high failure rate reflects the age and condition of these vehicles, with an average of 3.05 failures per test and 11.1 advisories suggesting multiple issues accumulate quickly.

These 520s are averaging 130,463 miles, which is relatively high for a 1996 model, and that mileage context explains why they're failing so frequently. Before buying one, get a pre-purchase inspection focused on the cooling system, suspension, and electrical gremlins that plague BMWs of this era, and budget for repairs rather than betting on a clean MOT.

What to check before buying a 1996 BMW 520

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.
  • ⚠️ 25.7% 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.
