1987 Renault R21

CarHunch analysed 114 real MOT records for the 1987 Renault R21. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1987 Renault R21 passes its MOT just 67.2% of the time, which is 12.8 points below the UK average—a significant reliability concern that suggests age-related wear is catching up with these nearly four-decade-old cars. With 12.3% of vehicles having recorded a dangerous defect at some point, buyers should expect to budget for safety-critical repairs before purchase.

These R21s are running at a median 90,950 miles, which is reasonable for their age, but they're averaging 1.32 failures per test and 4.1 advisories, pointing to accumulating issues across multiple systems rather than isolated problems. Before buying one, get a full pre-purchase inspection focused on brakes, suspension, and corrosion—the high advisory count suggests these are where money will go.

What to check before buying a 1987 Renault R21

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.
