The 2008 Mazda 6 fails to match the UK average, with a first-time pass rate of 72.9% against the 80% benchmark—a meaningful gap that reflects underlying wear issues on a 16-year-old model. More concerning is that 41.7% of these cars have recorded a dangerous defect at some point, well above typical thresholds, making pre-purchase inspection non-negotiable for any buyer.

These vehicles are running at a median 98,465 miles, which is substantial for their age, and they're racking up an average of 4.13 failures per test and 20.9 advisories—figures that point to cumulative age-related deterioration rather than isolated problems. If you're considering one, budget for imminent repairs (suspension, brakes, and emissions components feature heavily in the failure data) and have a trusted mechanic conduct a full inspection before you buy.

The 2008 Mazda 6 has a below-average first-time pass rate (72.9% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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
⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.
🔧 Expect consumable spend. An average of 20.9 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 11,218 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.
