Should I check the MOT history before buying a 2017 Mazda 6?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2017 Mazda 6 passes its MOT on first attempt 87.9% of the time, well ahead of the UK average of 80%, making it a genuinely reliable choice—though the 30.1% of vehicles that have recorded a dangerous defect at some point is a concern worth acknowledging. Petrol versions prove slightly more dependable than diesels (89.5% vs 86.9% pass rate), so fuel choice does matter here.

These cars are showing sensible mileage for their age, averaging 56,118 miles, which suggests typical use rather than high-mileage abuse. The average Mazda 6 will rack up nearly one failure per MOT cycle and pick up eight minor advisories, pointing to wear on consumables and minor components rather than structural issues—get a pre-purchase inspection to confirm service history and check for any previous dangerous defect flags before committing.

The 2017 Mazda 6 has a decent first-time pass rate (87.9%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 87.9% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 8.1 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 4,867 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
