Should I check the MOT history before buying a 2014 Mercedes Benz A Class?

The 2014 A-Class passes its MOT slightly more often than the UK average at 83.4% versus 80%, which is reassuring—but the alarming figure is that 42.6% of these vehicles have recorded a dangerous defect at some point, well above acceptable thresholds. Petrol versions fare noticeably better with an 86.3% pass rate compared to 63.7% diesels at 82.7%, suggesting the diesel engines are more prone to issues.

At 63,746 miles median, these nine-year-old cars are running below their expected mileage, which typically helps reliability. However, vehicles are averaging 1.89 failures and nearly 10 advisories per test, pointing to persistent wear items and component degradation—if you're considering one, budget for brake work, suspension repairs, and electrical gremlins, and always get a full pre-purchase inspection focusing on emissions systems and brake condition.

The 2014 Mercedes Benz A Class has a decent first-time pass rate (83.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ 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

🔧 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 9.9 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 24,825 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.
