Moderate sample. 379 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2012 Mercedes ML 250 passes its first MOT at 85.2%, which is a solid 5 points above the UK average, suggesting these diesels are generally well-maintained—though nearly 28% have recorded a dangerous defect at some point, which is a red flag worth investigating on any used example. The median mileage of around 69,000 is reasonable for a twelve-year-old SUV, but the average of 1.84 failures per vehicle indicates these aren't trouble-free; expect to budget for repairs.

With over 10 advisories per car on average, ageing components like suspension, brakes and seals need close attention on the pre-purchase inspection. Before committing, request the full MOT history and have a trusted independent specialist check the suspension and cooling system—common weak points on this generation Mercedes.

The 2012 Mercedes Ml 250 has a decent first-time pass rate (85.2%), 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
Good baseline reliability. A 85.2% 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 10.6 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 379 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.
