Citroen Cx (1986)

111 real MOT outcomes analysed • 66.5% first-time pass rate

1986 Citroen Cx

CarHunch analysed 111 real MOT records for the 1986 Citroen Cx. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1986 Citroën CX has a first-time pass rate of just 66.5%, well below the UK average of 80%, signalling that these nearly 40-year-old cars need more work to meet MOT standards. With almost one in five vehicles (19.8%) having recorded a dangerous defect at some point, buyers should view this as a car for enthusiasts rather than everyday transport.

These cars are averaging over 110,000 miles, which is high for their age, yet they're still racking up 2.17 failures and 6.2 advisories per test on average—a sign that wear and rust are catching up faster than mileage alone would suggest. Before buying, insist on a full pre-purchase inspection by a Citroën specialist, as the combination of high failure rates and dangerous defects means regular surprises will be expensive.

What to check before buying a 1986 Citroen Cx

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.
