Should I check the MOT history before buying a 2021 Toyota Aygo?

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 2021 Toyota Aygo?

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.

How are tyres and brakes typically on a 2021 Toyota Aygo?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Toyota Aygo reliable?

Based on MOT data from 16,564 vehicles, the 2021 Toyota Aygo has a first-time MOT pass rate of 93.9%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

What are common problems with the 2021 Toyota Aygo?

These figures are based on actual MOT test records — search a specific registration on CarHunch to see its individual history.

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2021 Toyota Aygo is genuinely reliable, with a 93.9% first-time pass rate that sits well above the UK average of 80%—and only 7% of vehicles have ever recorded a dangerous defect, which is low. These are nearly new cars averaging just 19,386 miles, so the strong pass rate reflects both solid engineering and minimal wear.

Owners should expect very few failures (0.2 per vehicle) but plan for minor advisories around routine items like wipers and fluids (1.6 per vehicle on average). Before buying, check the service history carefully and have a pre-purchase inspection focus on whether scheduled maintenance has been kept up, since these cars are forgiving only if they've been looked after properly.

The 2021 Toyota Aygo passes its MOT first time more often than most UK vehicles (93.9% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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 93.9% 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 1.6 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 16,564 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.
