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 2.4 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 975 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.
