Should I check the MOT history before buying a 2020 Ford Focus ST?

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 2020 Ford Focus ST?

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.

The 2020 Focus ST passes its first MOT at 89.6%, well above the UK average of 80%, suggesting this generation is mechanically sound—though the 21.4% rate of dangerous defects is a concern worth investigating on any example you're considering. With a median mileage of just under 26,000 miles, these cars are genuinely low-mileage four-year-olds, and the average of 0.44 failures per vehicle confirms they're holding up reliably so far.

Where owners do hit issues, they're typically minor: the average advisory count of 3.0 points to consumable wear (tyres, brakes, wipers) rather than structural problems. Before buying, get a full pre-purchase inspection and specifically ask the seller about any advisories on the last MOT—that'll flag early wear patterns and give you a realistic picture of what maintenance lies ahead.

The 2020 Ford Focus ST passes its MOT first time at roughly the UK average rate (90.3%) — solid but worth checking this vehicle's history carefully.

⚠️ 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

✅ Good baseline reliability. A 90.3% 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 3 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 1,339 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.
