This 2021 Mercedes-Benz C 220 diesel is more reliable than the UK average, with an 88% first-time MOT pass rate against the national 80%, and dangerous defects affecting only 8.9% of the fleet—well below concerning levels. The low failure rate of 0.19 per vehicle suggests these cars are mechanically sound when they arrive at test centres.

At 32,350 miles (median), these are relatively low-mileage examples for their age, which partly explains the strong pass performance. The 1.7 advisories per car indicate minor wear items cropping up but nothing alarming; if you're considering one, a pre-purchase inspection by a Mercedes specialist will confirm the service history and catch any developing issues before they become costly.

The 2021 Mercedes Benz C 220 Amg Line Edition D Auto 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.

⚠️ 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 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 1.7 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 618 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.
