Moderate sample. 335 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 Mercedes-Benz V 300 AMG Line D Auto passes its MOT first time at 84.5%, which is comfortably above the UK average of 80% — a solid result. However, 21.8% of vehicles in this cohort have recorded at least one dangerous defect during their MOT history, which is a genuine concern for a buyer and worth investigating in any used example.

At a median mileage of 39,502 miles for a four-year-old vehicle, these Merc vans are running fairly average wear, and the low failure rate of 0.5 per vehicle suggests major structural faults are rare. The 3.2 advisories per vehicle typically point to minor wear items rather than serious problems, but before committing to purchase, have any prospective buy independently inspected for previous dangerous defect history — particularly suspension and brake components.

The 2020 Mercedes Benz V 300 Amg Line D Auto passes its MOT first time at roughly the UK average rate (88.5%) — solid but worth checking this vehicle's history carefully.

⚠️ 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

✅ Good baseline reliability. A 88.5% 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 3.2 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 335 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.
