Mazda Rx 7 (1985)
1985 Mazda Rx 7
CarHunch analysed 133 real MOT records for the 1985 Mazda Rx 7. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1985 RX-7 passes its MOT first time only 67.7% of the time, well below the UK average of 80%, and nearly a quarter of these cars (22.6%) have recorded a dangerous defect at some point—a genuine safety flag for buyers. This is an ageing sports car with real reliability concerns, not a casual maintenance item.
With median mileage sitting at 87,000 miles for a nearly 40-year-old car, these survivors have been driven hard, and the average of 1.71 failures per vehicle reflects wear-and-tear issues typical of older Mazdas of this era. Before buying one, get a thorough pre-purchase inspection focused on the rotary engine, cooling system, and brakes—the advisory count of 6.0 per car suggests multiple minor issues are the norm, not the exception.
What to check before buying a 1985 Mazda Rx 7
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.
- ⚠️ 22.6% 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.
