Moderate sample. 374 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2010 Mercedes-Benz E350 BlueEFFICIENCY CDI is a serious reliability concern: just 42.8% pass MOT first time against the UK average of 80%, meaning nearly 6 in 10 fail. The bright spot is that dangerous defects are vanishingly rare at 0%, but the consistently poor pass rate across all 372 diesel examples suggests systemic weakness rather than isolated bad examples.

At 110,000 miles these cars are running high mileage for their age, yet they're still failing at roughly 1.2 defects per test—well above what you'd expect from normal wear. If you're considering this model, budget for immediate pre-purchase inspection by a Mercedes specialist, and factor in regular repair costs as non-negotiable running expenses rather than optional extras.

The 2010 Mercedes Benz E350 Bluef Cy Sport CDI A has a below-average first-time pass rate (74.2% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
