1998 Mazda Xedos 6
CarHunch analysed 369 real MOT records for the 1998 Mazda Xedos 6. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1998 Mazda Xedos 6 is a troublesome proposition on the used market, with a first-time MOT pass rate of just 66.4%—well below the UK average of 80%—and nearly one in five examples (19.2%) having suffered a dangerous defect at some point. This isn't a car to buy without a thorough pre-purchase inspection.
At around 97,000 miles on average, these cars have covered reasonable mileage for their age, but they're averaging over three failures per test and nearly ten advisories, pointing to widespread wear across multiple systems rather than isolated problem areas. Before making an offer, budget for immediate repairs and request the full MOT history to see which specific faults keep recurring.
What to check before buying a 1998 Mazda Xedos 6
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.
