Should I check the MOT history before buying a 2015 MG 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.

What corrosion should I look for when inspecting a 2015 MG 6?

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.

How are tyres and brakes typically on a 2015 MG 6?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2015 MG 6 falls slightly below the UK average with a 77% first-time pass rate, and more concerning, half of these vehicles have recorded a dangerous defect at some point—a notably high proportion that should give potential buyers pause. This is a diesel-only cohort, so the pass rate reflects the model's actual performance rather than a fuel-type split.

At 52,645 miles median, these six-year-old cars show typical mileage for age, but they're accumulating an average of 2.35 failures and 14.6 advisories per test, which suggests emerging wear and maintenance issues. If you're considering one, budget for imminent repairs—particularly around braking, suspension, and emissions systems—and ask the seller for full MOT history to check for patterns of dangerous defects.

The 2015 MG 6 has a decent first-time pass rate (77%), 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 14.6 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 506 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.
