This 2020 A 250 AMG passes its MOT on the first attempt 90.6% of the time, well ahead of the UK average of 80%, which signals a genuinely reliable petrol engine and chassis for this age and mileage. The dangerous defect rate of 10.2% is comfortably low, so you're not buying into a cohort with systemic safety problems.

At 35,000 miles median—conservative for a four-year-old car—these examples have been looked after, and the average of just 0.29 failures per test confirms they're holding up well. Advisories average 1.7 per vehicle, which is light wear; if you're considering one, a pre-purchase inspection focusing on the brake system and suspension will catch any outliers before you commit.

The 2020 Mercedes Benz A 250 Amg Line Premium + E A passes its MOT first time more often than most UK vehicles (92.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 92.7% 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 1.7 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 954 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.
