Should I check the MOT history before buying a 2006 Mazda B Series?

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 2006 Mazda B Series?

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.

Moderate sample. 337 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2006 Mazda B Series struggles to match the UK average, with a first-time pass rate of just 73.3% against the national 80% benchmark—a meaningful gap that suggests these trucks age less gracefully than most. More concerning, nearly 40% have recorded a dangerous defect at some point, which is well above acceptable thresholds for a buyer to ignore.

At an average mileage of just over 80,000 miles for an 18-year-old truck, these aren't low-mileage bargains, yet they're still accumulating serious wear: the average vehicle racks up nearly 5 failures per test and over 26 advisories, pointing to deteriorating brakes, suspension, and structural integrity. If you're considering one, get a thorough pre-purchase inspection focused on steering and brake components, and factor in near-certain upcoming repair costs.

The 2006 Mazda B Series has a below-average first-time pass rate (73.3% 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 26.4 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 337 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.
