Should I check the MOT history before buying a 2021 Vauxhall Astra Business Edition Nav T D?

For context

✅ Good baseline reliability. A 90.6% 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 1.8 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 597 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.
