This 2020 Mercedes-Benz CLA 220 AMG Line performs well above the UK average, with an 89.4% first-time MOT pass rate compared to 80% nationally, and a relatively low dangerous defect rate of 15.8% means serious safety issues are not widespread across the fleet. The diesel powertrain appears to be holding up reliably in this cohort.

At 36,900 miles average, these cars are running around the expected mileage for a four-year-old vehicle, and the low failure rate of 0.38 per vehicle suggests routine maintenance is keeping them in good shape. However, the 2.7 advisories per vehicle indicate minor wear is starting to show, so budget for small remedial work when buying used—and always insist on a full service history to confirm the previous owner kept up with Mercedes' maintenance schedule.

The 2020 Mercedes Benz Cla 220 Amg Line Premium + D A passes its MOT first time at roughly the UK average rate (91%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 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 91% 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 2.7 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 985 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.
